Thanks for reviewing, I agree with you.
I didn't consider that common case, but I think swizzleBGRAToRGBA seems have a problem.
In BitmapTextureGL::updateContents, const char *imageData should not be modified by swizzleBGRAToRGBA because 
1) const_cast used
2) seems to be shared textures which point same NativeImagePtr

A and B keep changing its data from BGRA to RGBA or from RGBA to BGRA. So, both A and B cannot have correct color simultaneously.
