- machine-independent glyph blt.
- assumes that glyph bits in snf are written in bytes,
-have same bit order as the server's bitmap format,
-and are byte padded. this corresponds to the snf distributed
-with the sample server.
-
- get a scratch GC.
- in the scratch GC set alu = GXcopy, fg = 1, bg = 0
- allocate a bitmap big enough to hold the largest glyph in the font
- validate the scratch gc with the bitmap
- for each glyph
- carefully put the bits of the glyph in a buffer,
- padded to the server pixmap scanline padding rules
- fake a call to PutImage from the buffer into the bitmap
- use the bitmap in a call to PushPixels
