  *TODO 
  * Rename stencil to mask
  * Test blend modes and name them correctly
- * Suppress old "blend", "fade" and "lines" stencil definition. Change all xml accordingly.
  * Improve perf: use LUT for alpha blending in uniform case
  * Improve perf: make sure filter is not called more than necessary in viewer (seems to be called 3 times per change)
  * Add gradient coloring as a filter
