    Optimize render passes with single quads
    
    Many effects (masks, replicas, filters) generate render passes for
    simplicity in the code.  However, in the cases where the pass contains a
    single quad with a texture, that resulting texture could just be used as
    the input texture instead of the render pass itself.
    
    The complication is mostly that render passes and tile textures are
    flipped relative to each other (oops) and so some knowledge of this has
    to leak into drawing render passes.
    
    This is done by detecting such render passes inside of DirectRenderer,
    storing the TileQuad that would have been drawn, skipping allocating the
    pass and rendering it, and then calling a slightly modified version of
    DrawRenderPassQuad with the TileQuad's resource.  The check for which
    render passes can be supported is conservative to start.
    
    This optimization usually will not be supported on mac because skia
    does not support textures with texture rectangle targets as input.
