  [truetype] Ingnore FT_LOAD_NO_BITMAP in bitmap-only fonts.
  
  For consistency with other bitmap-only fonts, we should ignore this
  flag of the font is not scalable.
  
  * src/truetype/ttgload.c (TT_Load_Glyph): Check if face is scalable
  when checking for FT_LOAD_NO_BITMAP.
  
  * docs/CHANGES: Start new chapter wtith this change.

	5	+ - Bitmap-only TrueType fonts now ignore FT_LOAD_NO_BITMAP flag and
	6	+ proceed loading bitmaps instead of giving an error. This behavior
	7	+ is documented and implemented for other bitmap-only fonts. The
	8	+ flag has always meant to suppress the bitmap strikes in favor of
	9	+ outlines, not to ban them completely.
