GL: make the double precision shader tests work on llvmpipe. It doesn't support GLSL 4.00 yet, but the extension alone is supported. 6 years ago			`#extension GL_ARB_gpu_shader_fp64: require`

GL: test setting at least some double uniforms. Needs to be improved to cover all types, but at least something. 8 years ago			`in vec4 position;`

			`uniform dmat4 matrix;`

			`void main() {`
			`gl_Position = mat4(matrix)*position;`
			`}`
