Hash :2f45d93d Message :Capture/Replay: Init shader outputs during self-tests.
This forces all uninitialized variables to have default values.
For instance if the application doesn't initialize the output
color, or a varying that's use in the output, this will ensure we
don't use any undefined values in the computation.
Found when working on a re-trace of T-Rex, which doesn't write to
the alpha channel in the final rendering pass. Also fixes undefined
values in GLSLTest.InactiveVaryingInVertexActiveInFragment.
