[Piglit] [PATCH 3/5] gles2: port clear-varray-2.0
Tom Gall

Thu Dec 20 10:54:01 PST 2012
Port testcase clear-varray-2.0 from tests/general into
tests/spec/gles-2.0 and update substantially for OpenGL ES 2.0.
Test checks that glClear and vertex attributes via
glVertexAttribPointer work correctly together.
