Subject: Vary fragment shader in separate shader random tests.
X-Git-Tag: upstream/0.1.0~1921^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5b6b88e78c917d9367258c0905cd7e85b8538471;p=platform%2Fupstream%2FVK-GL-CTS.git

Vary fragment shader in separate shader random tests.

- Use supplied random seed in genFrgShaderSrc to vary generated fragment
  shaders slightly. This prevents random test cases from always using
  identical fragment shader pipeline programs. Prior to this CL, the
  supplied random seed was unused.
