This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame. Two execution models: - Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation. - FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees. Operations are multi-threaded but do not run in parallel as Tiled (will be done in another patch). This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage. FullFrame breaking changes respect Tiled system, mainly: - Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation. - Any sampling is always done over inputs instead of last buffered operation.
