76f98008e8 gl_engine: optimize off-screen rendering
Performing a full-screen RenderPass resolve is too expensive.
Because most composite cases only require a small area to be rendered off-screen.
To improve performance, use the bounds of the Geometry for off-screen rendering whenever possible

9f105b60c4 common: Move the list to the gl_engine side.
Unfortunately, the usage of this list is not intuitive,
so can be confusing. Placed it only for gl.
