+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
