uxa: Enable SHM pixmaps
Now with streaming uploads and downloads for composite operations in
place, shared memory pixmaps are no longer that dire performance wise.
With careful use these can in fact be the most efficient means of
transfer between a wholly software renderer in the client and a backing
store. For instance, Chromium renders internally to an ARGB32 image
buffer and uses a shared pixmap to composite dirty regions into the
backing store. Thereby using the GPU to either perform the blit or the
format conversion. Enabling shared pixmaps, reduces our CPU overhead
whilst scrolling by a factor of 5 or so.
And this is achieved simply by deleting obsolete code!
