(not sure if this got posted)

Hi,
	I have a question regarding tiling rectangular areas
of a drawable.

In the course of writing a widget I have been considering the question of
tiling a rectangular area of a drawable.  I have tried the obvious way of
doing this, i.e., setting the tile attribute of a gc, the ts_x_origin,
ts_y_origin, and the fill style to FillTiled, and the not-so-obvious way,
i.e., doing it yourself.

In both cases I was using a Pixmap to tile a drawable.  I found (much to my
surprise) that the not-so-obvious way was MUCH faster (one my Sparcstation
1) with an area about twelve times the area of the tile.  This seems bizzare
to me, after all the obvious way requires one trip to the server, while the
not-so-obvious way requires many trips. 

Has anyone else noticed such behaviour, or have I most likely overlooked
something? 

The code is in a widget I am writing, so I do not include it here, however,
I will go off now and try and reproduce this in straight Xlib calls.  In the
meantime, if anyone has advice, flames (:-), etc., I'll be happy to receive
them, and will post a summary to the net if there is interest

(later....)

I've written two raw Xlib programs to demonstrate the problem. (Compile
with -lX11).
