IMHO not really (I guess this goes back to the bad old days when 
get/put buffers were opaque).

Probably "w*h*pixel_size" bytes where pixel_size is given by the above
equation or (GT_SIZE(mode.graphtype)+7)/8.  At least for unpacked
buffers (packed buffers can be requested using GT_SUB_PACKED_GETPUT
graphtype flag, although nothing implements them yet).

Cheers,
