Shader:hasUniform

Available since LÖVE 11.0
It has replaced Shader:getExternVariable.

Gets whether a uniform / extern variable exists in the Shader.

If a graphics driver's shader compiler determines that a uniform / extern variable doesn't affect the final output of the shader, it may optimize the variable out. This function will return false in that case.
