weird behaviour with color rendering

[Ann Crabbé]

Color rendering shows very weird behavior in the VIS tool. It always has done that but I never really given it much attention:

• When I turn off classes, those pixels should be transparent, but they go black or even one of the colors of the other classes
• At the edges between pixels there are edge effects of colors overlapping it seems
• Also changing the color sometimes has effect, sometimes it doesn’t.

Since you wrote most of the script, and your bigflagrenderen does something similar. Can you point me in the right direction to fix this? I have no idea what part of the code makes the colours change in the image.

I have seen this effect when developing the bitflagrenderer.
