This commit adds a set of APIs for iterating over the set of codepoints
for which the font provides a glyph. This implementation calls FreeType
directly to iterate over the charmap of font->face.
This is intended to be used in for loops as follows:
for (Uint32 ch = TTF_GetFirstFontChar(font); ch != UINT32_MAX;
ch = TTF_GetNextFontChar(font)) {
/* do something... */
}
