stricter format checks were introduced on GLES. This may lead to format

also check whether a bound texture format can also be read back from the
fbo and report the standard and additional formats also to the guest.

Not all compressed formats can be uploaded using glTexImage2D, that
only works if the extension provides an online texture-compressor. For
instance, EXT_texture_compression_s3tc only requires an online
compressor in the desktop version.
This test isn't really a test for the presence of an online-compressor,
this code is meant to test if we can render from it. But calling
glCompressedTexImage2D requires us to provide a valid compressed
payload, which is really awkward to maintain.
So let's instead just check for extensions to decide if these formats
are renderable or not.
Also, none of these compressed formats can be rendered to, so there's
no point in even testing for that.

Commit 84fc54f6bf introduced the use of RG
formats with a swizzle as backing store for guest requested LA formats.
This works for many cases (e.g. blitting), but unfortunately it can't be
used when rendering with blending to an LA target. Since GL doesn't
support texture write swizzles the swizzle needs to happen in the
fragment shader and that's too early for proper blending.
We can safely revert the offending commit since the tests fixed by it
have since been fixed by other commits (e.g., "vrend: Nop sends to
backing iovs for readonly textures v2") in a different way. The one
side effect of reverting is that, depending on the GL version, a less
efficient path may be taken in the guest Mesa when mipmapping LA formats
since they may not be considered color-renderable anymore.
