+Infinality Freetype Truetype Subpixel Hinting Patch
+-------------------------------------------------------------------
+Should patch cleanly to freetype-2.4.3
+
+
+Changes for 2010-11-14:
+ * Rule tweaks on various fonts. Fixed the Cyrillic y issue and e issue
+ with Trebuchet, and the ^ issue with Arial. Other issues
+ (firefox and @font-face) are still present to a degree.
+
+ * A couple new rules to deal with various issues. (work in progress)
+
+ * Additional commenting.
+
+ * Some cleanup of obsolete code.
+
+ * Added some debugging code for potential future enhancements. Please
+ ignore the mess.
+
+
+Changes for 2010-10-22:
+ * I'm refocusing on just getting the subpixel looking nice, so I've stripped
+ back the rendering modes to just 2. The standard SUBPIXEL_HINTING and
+ the ADDITIONAL_TWEAKS. The rules structure is still in place. I recommend
+ using ADDITIONAL_TWEAKS mode.
+
+ * Fixed an issue with monochrome rendering that made fonts look really bad.
+ There is still an issue with them, but they are at least tolerable to
+ look at now.
+
+ * Added some testing code for detecting inline delta functions. Not sure
+ if this is useful yet.
+
+ * Added more rules to deal with certain artifacts on various fonts, like the
+ issue with < > and ^. Created some "exception" rules for certain rules.
+
+ * Reverted back to older rounding functions. The new experimental ones I
+ was trying were causing artifacts on some fonts.
+
+ * Some code cleanup.
+
+
+Changes for 2010-10-08:
+ * Fix PDF crashes.
+
+Changes for 2010-10-04:
+ * Update to freetype-2.4.3
+
+
+Changes for 2010-10-03:
+ * There are lots of changes for this one, some big, some small, and some
+ that still are not implemented. Not sure if I can remember them all
+ but I will try! THIS IS A POINT RELEASE THAT IS NOT
+ INTENDED TO WORK 100%. Some fonts and compile options may be broken
+ and the code may be inefficient and/or not syntactiacally correct.
+ That said, I do plan on using this on my system right away.
+
+ * There are now "rendering modes" for the subpixel hinting, with the idea
+ that this will enventually be able to be controlled by fontconfig. The 4
+ modes of enhanced hinting defined so far are:
+ 1) NATIVE HINTING - this is what freetype TT interpreter does by default.
+ 2) FIXED NATIVE HINTING - A slighly tweaked version of the above that
+ does "better" native rendering when displaying on LCD, for those
+ that still seem to like incorrect, thin fonts, which were only ever
+ there due to technical limitations.
+ 3) SUBPIXEL OPTIMIZED HINTING - this is straight up subpixel hinting with
+ very few tweaks. Just enough to get it working.
+ 4) COMPATIBILITY MODE HINTING - this is the sweet spot I'm working on
+ that will hopefully supplant #3 because it will work so well with all
+ fonts. The idea here is to tweak all available fonts so that each
+ renders well.
+ All of these modes either turn on or off switches in the interpreter
+ to make the fonts render properly for each mode. Right now these are only
+ compile-time options.
+
+ * Subpixel-related code has been broken out into its own files, so as to not
+ clutter up the existing code.
+
+ * The rasterizer now pays attention to the additional bits of MS rasterizer
+ v. 37, meaning that it can now indicate to fonts that it can handle
+ subpixel rendering.
+
+ * The rounding functions have been adapted to accept a grid resolution
+ variable, which lets them work on pixel and subpixel boundaries
+ automatically. Y still needs to be implemented.
+
+ * Additional conditions have been added to the switches, to further refine
+ how they are applied to different fonts.
+
+ * What all this means qualitatively is that legacy fonts now render much
+ better. There are still some that need a bit of love, like Courier New.
+
+ - Courier New has some fixes, and some breakage (Ghost pixels above bold
+ fonts, too thin on regular font)
+ - Times New Roman has some fixes and breakage (serifs, particularly)
+ - Tahoma and Trebuchet MS have been cleaned up
+ - Arial now snaps to grid better, but that causes breakage on a few glyphs
+ - Verdana 13 is now set to grid fit, but some glyhs are broken (mwxyz)
+ - Geneva and Geneva CY no longer look like turds
+ - Lucida Sans Unicode now looks arguably better than Lucida Grande
+
+
+
+Changes for 2010-09-16:
+
+ * The changes from 2010-09-14 regarding subpixel when LIGHT hinting enabled
+ have been reverted due to problems. The old behavior is back.
+
+ * Disable grayscale when subpixel is enabled. This results in better
+ behavior of some TT instructions within some fonts, like Times New Roman.
+
+ * Some modification of the tweaks, in light of above.
+
+
+Changes for 2010-09-14:
+
+ /************************** NO LONGER IN PLACE *****************************/
+ * Subpixel hinting is now used when the LIGHT hinting method and the TT
+ hinting is called. If FULL hinting is requested it will do the usual
+ behavior of the TT hinter.
+
+ This allows for all previously existing behavior, plus the new subpixel
+ hinting behavior, all in the same compile, and it makes sense in that
+ the slight hinting of the autohinter is essentially doing the same thing
+ as this, which is not forcing X-direction hints.
+
+ Previously, even if TT was selected, but LIGHT hinting was used, the
+ autohinter would still be forced. Other than this, autohint is not affected.
+ /***************************************************************************/
+
+ * Added a couple more conditionals around things to test whether subpixel
+ hinting is enabled. There were a few missing that ended up causing some
+ goofy hinting if subpixel was not enabled, but compiled in.
+

+freetype-entire-infinality-patchset (excludes the TT subpixel patches)
+-------------------------------------------------------------------
+
+This patch contains all the patches I used to distribute separately.
+It made more sense to lump these all together into a single file
+now that there are runtime options. It's also easier for me to maintain. ;)
+
+I recommend that if you are using this patch that you use
+
+ /etc/fonts/local.conf
+
+that I provide at: http://www.infinality.net/files/local.conf
+You will also need: http://www.infinality.net/files/infinality-settings
+
+The second one will need to be included in your profile with something like:
+
+ . ~/path/to/the/file/infinality-settings
+
+It should be adjusted to your personal tastes as an end-user.
+
+
+DISCLAIMERS:
+
+This patch will almost certainly result in a performance hit when
+freetype is rendering the glyphs. The good news is that fontconfig
+caches the glyphs so it's only the first time they are displayed that there
+could be a performance issue.
+
+I expect that if you compile freetype with this patch along with my
+TT subpixel hinting patch, you will have a complete build that works the
+way I expect it to. However, I have not tested all compile configurations
+for errors. I intend to at some point. This patch may make your system crash,
+have memory leaks, not compile, or render fonts in a way that you don't like.
+Either way, when you use this patch, you should recognize that it
+is ALPHA / BETA quality. That said, I intend to run these patches on my
+personal system, so they had better be pretty stable!
+
+
+Changelog
+
+2010-11-14
+ - All patches can now be enabled at runtime with ENVIRONMENT_VARIABLES.
+ See the file infinality-settings (and below) for how to enable these.
+ Effects that used to work now **REQUIRE** these in order to be turned on
+ at runtime. This lets end users have full control over what they want
+ without requiring different compiles.
+
+ - Added option to auto-embolden thin/light fonts.
+
+ - Further refinement of the stem calculations for enhanced autohint.
+
+ - Adjustable FIR filter at runtime.
+
+ - Stem alignment ability to align glyph bitmaps to pixel boundaries.
+
+ - Adjustable gamma correction prior to the FIR filter for LCD rendering.
+ This can be used to make small ppem text more readable, or for whatever
+ else you want to use it for.
+
+ - A height tweak on the enhanced autohint that makes Arial, Segoe, Times
+ and others render more similarly to Windows.
+
+ - Separated out the option to maintain the original width of glyphs
+ when doing fake emboldening.

+# INFINALITY_FT_FILTER_PARAMS
+#
+# This is a modified version of the patch here:
+# http://levelsofdetail.kendeeter.com/2008/12/dynamic_fir_filter_patch.html
+#
+# Allows you to adjust the FIR filter at runtime instead of at
+# compile time. The idea is to have values add up to one, and be
+# symmetrical around the middle value. Here are some samples
+# of various filter parameters:
+#
+# Strong Extra Smooth "0.15 0.2 0.3 0.2 0.15" (extra smooth, natural weight)
+# Extra Smooth "0.20 0.20 0.30 0.20 0.20" (extra smooth, extra weight)
+# Smooth "0.15 0.20 0.32 0.20 0.15" (smooth, natural weight)
+# Stronger Gibson "0.11 0.22 0.38 0.22 0.11" (smooth, extra weight)
+# Gibson "0.11 0.22 0.33 0.22 0.11" (smooth, natural weight)
+# Freetype Light "0.00 0.33 0.34 0.33 0.00" (sharp, natural weight)
+# Freetype Default "0.06 0.25 0.44 0.25 0.06" (sharp, extra weight) *default
+# Extra Sharp "0.00 0.35 0.35 0.35 0.00" (extra sharp, extra weight)
+#
+# Default: [Freetype's default]
+# Recommended: "0.11 0.22 0.38 0.22 0.11"
+#
+# Example 1: export INFINALITY_FT_FILTER_PARAMS="0.11 0.22 0.38 0.22 0.11"
+#
+
+export INFINALITY_FT_FILTER_PARAMS="0.11 0.22 0.38 0.22 0.11"

+# INFINALITY_FT_STEM_ALIGNMENT_TYPE
+#
+# This performs analysis on each glyph and determines the best
+# subpixel orientation for the glyph. The glyph is not scaled in
+# any way, just moved left or right by a subpixel amount. This
+# results in subtley cleaner looking fonts, at the expense of
+# proper distances between glyphs. This is only active for sizes
+# 10 px or greater and does not apply to bold or italic fonts.
+#
+# Possible values:
+# full - Allows a glyph to be moved to the LEFT or RIGHT by 1 subpixel
+# Best alignment, Worst positioning

+INFINALITY_FT_AUTOFIT_STEM_SNAP_LIGHT details
+---------------------------------------------
+
+This patch is intended to make freetype's autohinter round down widths of
+horizontal stems to whole pixel values. This dramatically reduces the
+graininess of the rendering at small sizes, at the expense of being true to the
+glyph.
+
+Put simply, it makes freetype's autohinter render fonts similarly
+to well-hinted TrueType fonts, even on fonts that contain no instructions.
+So, as far as I can tell, this makes it 100% patent-free.
+
+The most dramatic results are on sans-serif fonts like Lucida Grande,
+Arial, Helvetica Neue, Inconsolata, Droid Sans, Trebuchet MS, etc.
+
+
+It is recommended to use this with antialiasing on, and fonts set to
+slight hinting:

+#
+# This is a modified version of the patch here:
+# http://levelsofdetail.kendeeter.com/2008/12/dynamic_fir_filter_patch.html
+#
+# Allows you to adjust the FIR filter at runtime instead of at
+# compile time. The idea is to have values add up to one, and be
+# symmetrical around the middle value. Here are some samples
+# of various filter parameters:
+#
+# Strong Extra Smooth "15e-2 20e-2 30e-2 20e-2 15e-2" (extra smooth, natural weight)
+# Extra Smooth "20e-2 20e-2 30e-2 20e-2 20e-2" (extra smooth, extra weight)
+# Smooth "15e-2 20e-2 32e-2 20e-2 15e-2" (smooth, natural weight)
+# Stronger Gibson "11e-2 22e-2 38e-2 22e-2 11e-2" (smooth, extra weight)
+# Gibson "11e-2 22e-2 33e-2 22e-2 11e-2" (smooth, natural weight)
+# Freetype Light "00e-2 33e-2 34e-2 33e-2 00e-2" (sharp, natural weight)
