Each active uniform is assigned 46 a value using an appropriate glProgramUniform* function, either the pointer 47 variant or the value variant (if possible; for instance, matrices can only be 48 assigned using the pointer variant). Arrays with basic element type can have 49 their first element identified using either just the array's name or that 50 appended with "[0]"; both methods are tested. 51 52 To verify that the correct uniform values were assigned, either the uniform 53 values are queried with glGetUniform* or the shaders are rendered with; the 54 shaders are constructed such that the result should be an all-green quad if 55 the uniforms have correct values, and all-black otherwise. 56 57 At the beginning of each test case, a dummy program is created and made active 58 with glUseProgram; otherwise, the glProgramUniform* calls would behave just as 59 the corresponding glUniform* calls. 60
