   - Will be added in 2014.4 release

Description:

Valid cases compile and run a program that perform the operation under test
in either vertex and fragment shader. Results are checked against reference
values in the shader code and either black or white color is selected based
on that. The test verifies that all result pixels are white.

Negative cases attempt to compile a shader with the invalid operation and
checks that the compilation in fact fails.
