tdf#103804 reduced register areaScale shader and detection for intel
Some intel drivers crash when areaScale shader with "large" array
is used. This adds a "reduced register" version of the areaScale
shader. We still use the first version of the shader for other
drivers and switch between the 2 implementations with a runtime
detection.
