+Problem description: Tab-titles that are too long to fit into a tab get faded out.
+                     On big endian this is broken and instead of fading out, the 
+                     tab gets white and the font transparent, leading to an unreadable
+                     tab-title
+Solution: This is not a real solution, but a hack. The real solution would have been
+          to byte-swap the correct buffer, but I could not find it.
+          So the next best thing is to deactivate the fading-effect. Now all tab-titles
+          are readable, albeit not as pretty to look at as they could be. 
+Side-effects: I have not yet found an unwanted side-effect.

+Problem:  webGL sites are displayed in the wrong color (usually blue-ish)
+Solution: Problem is with skia once again. Output of webgl seems endian-correct, but skia only
+          knows how to deal with little endian.
+          So we swizzle the output of webgl after reading it from readpixels()
+Note:     This does not fix all webGL sites, but is a step in the right direction
