[WIN32K]
When adding new glyph cache entry convert the glyph bitmap with proper alignment to comply
with the new code in EngCreateBitmap and remove the corresponding hack from
SURFMEM_bCreateDib.
[FREETYPE]
When doing 1BPP -> 8BPP conversion set all 8 bits not only the LSB. (Freetype devs were
notified of this issue)
See issue #5244 for more details.
