With Alpha channel and Raster Operations, why it is so difficult to implement this color strip feature ?
Maybe the theme editor have to implement an alpha channel tool. Then, a simple raster operation with track color and "alpha channelled" image would do the trick. How is it done with Mercury Theme ? Mercury Theme has probably some alpha channel information...
Okay, on the paper it seems to be easy, it's probably more complicated with existing code...
Hope the bakers will found a solution.
