    glamor_composite: Allocate VBO on demand.
    
    Use a fixed VBO is not efficient. Some times we may only has less than
    100 verts, and some times we may have larger than 4K verts. We change
    it to allocate VBO buffer dynamically, and this can bring about 10%
    performance gain for both aa10text/rgb10text and some cairo benchmarks.

    glamor_getimage: Add the optimization path of getImage.
    
    This optimization will only call glReadPixels once. It should get
    some performance gain. But it seems it even get worse performance
    at SNB, disable it by default.

    Set filter to GL_NEAREST by default.
    
    This is the fastest filter and let's use it by default.

    glamor-composite: Use glDrawElements to reduce the count of vertices.
    
    To split a rectangle (0,1,2,3) to two separated triangles need to feed
    6 vertices, (0,1,2) and (0,2,3). use glDrawElements can reuse the shared
    vertices.

commit 9291ead8bd18408cdff39ff0d559aaa209537199

    glamor-composite: Optimize the computation of composite region.
    
    Computing the composite region at the composite_with_shader is very
    inefficient. As when we call to here from the glamor_glyph's temproary
    picture, we don't need to compute this region at all. So we move this
    computing out from this function and do that at the glamor_composite
    function. This can get about 5% performance gain for aa10text/rgb10text.
