* include/freetype/ftgasp.h, src/base/ftgasp.c: adding a
new API FT_Get_Gasp to return entries of the GASP table
corresponding to a given character pixel size.

- Various memory leaks have been found and fixed.
+ - Fixed the TrueType name loader that didn't deal properly with some
+ fonts that encode their names in UTF-16 (the spec was vague, and
+ the code assumed UCS-4)
+
+ - Fixed the TrueType bytecode loader to deal properly with subtle
+ monochrome/gray issues when scaling the CVT. Some fonts exhibited
+ bad rendering artefacts otherwise.
+
+ - FT_GlyphSlot_Embolden now supports vertical layouts correctly
+ (it mangled the vertical advance height)
+
+ II. NEW API FUNCTIONS
+
+ - FT_Library_SetLcdFilter allows you to select a special filter to
+ be applied to the bitmaps generated by FT_Render_Glyph when one
+ of FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V is used. This
+ filter is used to reduce color-fringes, several settings are
+ available through the FT_LCD_FILTER_XXX enum.
+
+ See its declaration and documentation in FT_LCD_FILTER_H, a.k.a.
+ include/freetype/ftlcdfil.h.
+
+ *IMPORTANT*: note that this function returns an error
+ (FT_Err_Unimplemented_Feature) in default builds of the library
+ for patent reasons. See below
+
+
+ - FT_Get_Gasp allows you to query the TrueType GASP flags for a
+ given character pixel size. This is only useful to duplicate
+ Windows' text rendering, when the native bytecode interpreter is
+ enabled (which still isn't the default for other patent reasons)

+ III. IMPORTANT CHANGES
+
+ - The auto-hinter has been severely tuned to improve its results
+ with serif fonts. This results in much better font rendering of

The displayed result should be equal to normal anti-aliased
rendering.

- Some computation bugs in the TrueType bytecode interpreter were
found, which allow us to get rid of very subtle and rare
differences we had experienced with the Windows renderer.

III. MISCELLANEOUS
- - TrueType glyph loading is now about 25% faster.
+ - Various performance and memory footprint optimizations have been
+ performed on the TrueType and CFF font loaders, sometimes with
+ very drastic benefits (e.g. the TrueType loader is now about
+ 25% faster, FreeType should use less heap memory in nearly all
+ conditions)
