2319fcd228 OPENGL: Handle GLES2 and GL shaders uniformly.
GLES2 requires precision qualifiers to be set and allows use of precision
qualifiers. For GLES2 we define a default precision now. Since precision
qualifiers are not supported in the GLSL version we use for GL, we
introduce compatibility #defines.
