Add the SH_TIMING_RESTRICTIONS compile flag and dependency graph implementation. Description of the algorithm: http://code.google.com/p/mvujovic/wiki/ShaderControlFlowAnalysis This flag is one potential solution to timing attacks on textures containing cross-domain content or user agent data. This kind of analysis could be useful for both WebGL and CSS Shaders. The SH_TIMING_RESTRICTIONS flag will reject a shader if it uses texture dependent data to affect control flow. Other ways of affecting shader timing such as using NaNs in basic arithmetic operations or using built-in functions (e.g. atan) with different inputs are still under investigation.
