Fix for MTR Framebuffers

Browse Source 
The problem: Happens with two MTR framebuffers with same number of color attachements.
If we set a frame buffer frame1, then later frame2.
r.setFrameBuffer(frame1);
r.setFrameBuffer(frame2);
Frame2 buffer will not output to multiple targets. Only its first target will be rendered.
This patch fixes that problem.
