test app

After upgrading OLPC XO-1 from Fedora 14 (xorg-server-1.9) to Fedora 17
(xorg-server-1.12) we are seeing problems with GNOME's notification area. The
icons appear all-black, which is the same colour as the GNOME panel which they
are drawn upon.

I've narrowed this down to a simple test case (attached). This program draws an
icon (works OK), then when the window is resized the icon is replaced with
all-black.

Initial diagnosis at http://dev.laptop.org/ticket/11860 suggests that we're
receiving a composite PictOpSrc request with no mask, repeats or
transformations.
lx_do_composite then reacts in this way:

        /* All black out of the source */
        if (!exaScratch.repeat && (exaScratch.type == COMP_TYPE_ONEPASS)) {
            lx_composite_all_black(srcOffset, exaScratch.srcWidth,
            exaScratch.srcHeight);
        }

and the icon goes black.

We are not 100% sure if this is a Geode bug or something wrong in the X server.
A good first step would be to understand how the driver should respond to
PictOpSrc with no mask, repeats or transformations, and if that is even valid
at all.
