Thanks for the report, I think I know why this is happening but I don't have access to a Linux Intel box for a couple weeks. Will fix then.

cwallez: Have you been able to figure out what's happening here?

FramebufferGL: Fix blit workaround corner case

The SRGB blit workaround had to wrong assumptions:
 - SRGB blits can have a multisample source.
 - The woarkound is needed even when the filter is GL_LINEAR in the
   case where we are doing a RGB -> SRGB or RGB -> SRGB blit.

WebGL CTS: remove now passing expectations.

Most of them come from implementing a work around for blits on Intel.
