[2.2.3][GL3Plus] No way to disable gamma/sRGB conversion?

[Scorg]

Hello.

While porting from 2.1 to 2.2.3 I have noticed that hardware sRGB conversion is enabled and cannot be disabled neither with "sRGB Gamma Conversion" option, nor the "gamma" option to Root::createRenderWindow(). I have tracked the cause to an unconditional glEnable( GL_FRAMEBUFFER_SRGB ) in GL3PlusRenderPassDescriptor::performLoadActions(). This causes actually incorrect colors (brighter, pow'ed to 1/2.2 or so) to be put out.

I wonder what was the reason to force HW sRGB conversion, because my very limited knowledge about OpenGL suggests that there is no way for me to revert this conversion before displaying the framebuffer. I suspect it has something to do with texture loading/sampling, or possibly be a bug somewhere.

If necessary, I will provide screenshots showing the problem, though it's basically a darker (2.1) vs brighter (2.2) image.

This is a bug. Fixed.

Thanks for the report!
