[cairo] [PATCH 3/6] gl: Replace ftransform() with manual coordinate calculation in shaders

[alexandros.frantzis at linaro.org]

From: Alexandros Frantzis <alexandros.frantzis at linaro.org>

The ftransform() shader function was deprecated and removed in recent
GLSL versions and is not included at all in GLSL ES.
