65 /* Put and Get images on a monochrome frame buffer
67 * we do this by creating a temporary pixmap and making its
68 * pointer to bits point to the buffer read in from the client.
69 * this works because of the padding rules specified at startup
71 * Note that CopyArea must know how to copy a bitmap into the server-format
74 * For speed, mfbPutImage should allocate the temporary pixmap on the stack.
76 * even though an XYBitmap and an XYPixmap have the same
77 * format (for this device), PutImage has different semantics for the
78 * two. XYPixmap just does the copy; XYBitmap takes gc.fgPixel for
79 * a 1 bit, gc.bgPixel for a 0 bit, which we notice is exactly
