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
