[Mesa-dev] [PATCH v2] gallium/auxiliary/vl: Fix transparent issue on compute shader with rgba

[Zhu, James]

Bugzilla bug 109646 - New video compositor compute shader render glitches mpv
https://bugs.freedesktop.org/show_bug.cgi?id=109646
Problem 1,4: they are caused by imcomplete blend comute shader
implementation. So Reverts rgba back to frament shader from
commit	9364d66cb7f7deb83876a44bb4e29e8105141c16.
