Description
Created by: codeanticode
After applying a filter() on a P2D/P3D surface, the contents of the backing texture do not reflect the output of the filter operation. This becomes apparent in this issue reported in the Syphon library: https://github.com/Syphon/Processing/issues/32
The backing texture gets updated in the next frame (probably due to front/back texture swapping), but not clear why the backing texture is not ready by the end of the current frame

Research direction
The issue names no source files or tests; start by reproducing the filter() behavior on a P2D/P3D surface and tracing how the backing texture is updated during the frame. Compare the behavior with the Syphon issue, and consider the work done when the backing texture reflects the filter output by the end of the current frame.
