/**
* \file double_in_bool_uniform.c
*
* Tests that glUniform works as specified for trying to using the double
* interfaces with a bool uniform.
*
* The GL_ARB_gpu_shader_fp64 specification says in the Issues section:
* "(15) Can the 64-bit uniform APIs be used to load values for uniforms of
* type "bool", "bvec2", "bvec3", or "bvec4"?
* RESOLVED: No. OpenGL 2.0 and beyond did allow "bool" variable to be
* set with Uniform*i* and Uniform*f APIs, and OpenGL 3.0 extended that
* support to Uniform*ui* for orthogonality. But it seems pointless to
* extended this capability forward to 64-bit Uniform APIs as well."
