+/* Put and Get images on a monochrome frame buffer

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