WebGL: validate texture format matches sampler type WebGL requires that drawing produces INVALID_OPERATION if a texture's format doesn't match the sampler type it is bound to. This is a little confusing because samplers have two attributes that could be called "type": addressing mode (2D/3D/Cube), and component format (float/signed/unsigned/shadow). ANGLE already handled checking the addressing mode; this change adds checking for the component format.
