Actually, I found another compilation problem using the git version of
xcb and xcb_image a few days ago (sorry for late to report)

The problem is, when compiling,

Seeing the code, the cause is maybe the modification for cache change
is not sufficient for the software_xcb engine.
Then, I enabled the compiling with --enable-software-xcb by the attached patch.
Modifications by the patch are, roughly,
1. Copying outbuf_new_for_update function from software_x11 engine to
software_xcb engine.
2. Modifying function calls of the engine in the outbuf_new_for_update
from evas_software_x11_foo to evas_software_xcb_foo.
Now, I'm testing whether there are problems by applying the patch.

Is this patch something wrong?

P.S. compiling with --enable-xrender-xcb has problem, too.
I try to the fix this. But it seems to take a little time.
