an FT_Bitmap structure in 1bpp, 2bpp, 4bpp, or 8bpp format into
another 8bpp FT_Bitmap, probably using a different pitch.
- The method how BDF and PCF bitmap fonts are accessed has been
refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size
were synonyms in FreeType's BDF and PCF interface. This has
changed now. FT_Set_Pixel_Sizes should be used to select the
actual font dimensions (the `strike', which is the sum of the
`FONT_ASCENT' and `FONT_DESCENT' properties), while
FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE'
property). In both functions, the width parameter is ignored.
