Compositor: Constant folding Currently there is no clear way to know if an operation is constant (i.e. when all rendered pixels have same values). Operations may need to get constant input values before rendering to determine their resolution or areas of interest. This is the case of scale, rotate and translate operations. Only "set operations" are known as constant but many more are constant when all their inputs are so. Such cases can be optimized by only rendering one pixel. Current solution for tiled implementation is to get first pixel from input. This works for root execution groups, others need previous groups to be rendered. On full frame implementation this is not possible, because buffers are created on rendering to reduce peak memory and there is no per pixel calls. This patch evaluates all operations that are constant into primitive operations (Value/Vector/Color) before determining resolutions.
