This directory contained a single test, gles2_shader_runner, that was
never used. It was a failed artifact from the time when we were scrambling
to discover how to support GLES2 in piglit. Instead, GLES functionality
has been added to the real shader runner, tests/shaders/shader_runner.c.

In the future, any tests specific to GLES2 should go into the directory
tests/spec/gles-2.0, just as we do for all other GL versions.
