#2460: Fix getBoolean(GLExt.GL_FRAMEBUFFER_SRGB_CAPABLE_EXT) causes error 1280 (invalid enum)

[capdevon]

GL_FRAMEBUFFER_SRGB_CAPABLE_EXT is likely not a queryable state via glGetBooleanv. It's a capability flag for configuring framebuffers, not for querying the global sRGB state. It's good that it's commented out.

This PR should fix #1996

GL_FRAMEBUFFER_SRGB_CAPABLE_EXT is actually queryable via glGetBooleanv, but it is provided by the EXT_framebuffer_sRGB extension.

I suspect that some drivers that provided opengl3+ capabilities, do not implement a fallback for this extension.

Since this check is only used for debugging purposes and, as noted, it is not reliable across different platforms, i am ok with removing it.
But this PR needs to be cleaned from the unrelated formatting and logging changes, can you do that?

Thanks
