Matthias Clasen 686e627bdf [paint] Set up root transform in one place
Instead of spreading this in all the tables,
make hb_paint_funcs_t provide a push/pop_root_transform
that does all the setup.

VarC: cast ints (#3934)
msvc is rightfully complaining that the types on the sides of

```
C:\pango\subprojects\harfbuzz\src\OT\glyf\VarCompositeGlyph.hh(317): error C2446: ':': no conversion from 'const OT::HBUINT16' to 'const OT::HBUINT8'
