Description

Currently, the OpenGL plugin does not support multisampling. It should.

The approach will be to enable multisampling on the current main render
buffer, and create an additional render buffer as resolve target.

We'll change the Renderer::GetRenderTarget to
Renderer::ResolveAndGetRenderTarget(TRectangle &rect) which, if multisample
is enabled, will use glBlitFramebufferEXT() to resolve that rectangle to
the resolve target and return the identifier of the resolve target. In case
of multisampling disabled, it will just return the ordinary render buffer
as usual.

We'll have to do the same for the Z buffer target.

I plan to get this done in the coming week or two - if someone else wants
to do it now, go right ahead but tell me first.

is bad. metroid Prime: Scan Visor is all Black. Star Wars Force Unleashed. Wont
Start, all black but fps counter is running. all you see is the loading logo no more.

Something i noticed about the Metroid Scanner, which might help figuring out the
problem is that, when switching to the scanner with AA enabled, u first get the
correct image, but it seems to zoom infinitely thus resulting in a "HOM" effect being
seen instead.

What i mean is that maybe the previous conditions should be met for it to pop-up,
aka, the game being about to hang due to <1 fps.
