Werner Lemberg 559727d519 Change dimension fields in `FTC_ImageTypeRec' to unsigned type. 
This doesn't break ABI.

* include/ftcache.h (FTC_ImageTypeRec): Use unsigned types for
`width' and `height'.

* docs/CHANGES: Document it.
 2015-02-25 06:59:02 +01:00
Werner Lemberg 3d3523f721 Remove invalid note. 2015-02-25 06:46:13 +01:00
Werner Lemberg 4b9234b8a2 [cache] Don't use `labs'. 
This is the only place in FreeType where this function was used.

* include/config/ftstdlib.h (ft_labs): Remove.

* src/cache/ftcimage.c (ftc_inode_weight): Replace `ft_labs' with
`FT_ABS'.
 2015-02-25 06:31:43 +01:00
Werner Lemberg 3aaebe3a91 [cache] Replace `FT_PtrDist' with `FT_Offset'. 
* src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t')
is a better choice for `hash' to hold a pointer than `FT_PtrDist'
(a.k.a. `ptrdiff_t'), especially since the latter is signed,
causing zillions of signedness warnings.  [Note that `hash' was of
type `FT_UInt32' before the change to `FT_PtrDist.]
Update all users.

* src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccmap.c,
src/cache/ftcglyph.c, src/cache/ftcglyph.h: Updated.
