* builds/toplevel.mk: In `make dist`, checkout gnu-config
git repository at savannah, copy the latest versions of
`config.guess` and `config.sub` to builds/unix/. Also
the latest version of `gitlog-to-changelog` is used to
generate `ChangeLog`.
The behaviour changed in GNU make 4.3, where `#` (without the backslash)
would be necessary. Using a variable instead the code works with both older
and newer GNU make versions.
Fixes#1252.
* src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration values
`FT_COLR_PAINTFORMAT_INTERNAL_VAR_SKEW`,
`FT_COLR_PAINTFORMAT_INTERNAL_SKEW_CENTER`, and
`FT_COLR_PAINTFORMAT_INTERNAL_VAR_SKEW_CENTER`.
(read_paint): Handle new enumeration values.
