* docs/CHANGES: updating documentation
* docs/CHANGES: Updated.
* include/freetype/ftgasp.h, src/base/ftgasp.c: adding a
new API FT_Get_Gasp to return entries of the GASP table
* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add
a new API `FT_Get_Gasp' to return entries of the `gasp' table
corresponding to a given character pixel size.
* src/sfnt/ttload.c: add version check for the GASP table,
in order to be better future-proof
* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
`gasp' table, in order to avoid potential problems with later
versions.
* include/freetype/config/ftheader.h: add definition of
FT_GASP_H, corresponding to <freetype/ftgasp.h>
* include/freetype/config/ftheader.h (FT_GASP_H): New macro for
<freetype/ftgasp.h>.
* src/base/rules.mk, src/base/Jamfile, modules.cfg,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: Adding src/base/ftgasp.c
to the default build
* src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),
modules.cfg (BASE_EXTENSIONS), builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: Add src/base/ftgasp.c to the
default build.
