- Test ability to switch color spaces without performing actual change in the pixel values when changing only the color profile, but remaining with the same color model and depth.
- Test the above with files having different color model and depth.
- Test behavior when changing color model and depth.
NOTE: Limited test of the patch was done with 16bit/channel RGB file with selected mode "RGB/Alpha" and switching to "CMYK/Alpha". Seem to work fine with exception of the case when the "Channels" docker is shown - it seems to crash while trying undo-redo because of refresh issues.
