Is there an extension to the X Server available that supports the
oversampling (and undersampling) of pixels?  The corresponding
"Xlib" call might be a variant on XPutImage:

	XZoomImage(display, drawable, gc, image, src_x, src_y,
	           dst_x, dst_y, width, height, xfactor, yfactor )

xfactor and yfactor would be the integer replication factors.  Factors
greater than 1 would zoom an image, factors less than -1 would dezoom
an image (0,-1, and 1 would be defined to have no effect).

If so, where might it be available, and any impressions on the
difficulty of integrating an extension into our server?  Thanks.
