    Bug 699201: Fix alignment of rendering bands memory
    
    The bottom section of the "raster buffer", when rendering through the page
    clist, is reserved as a cache (tile cache, to be specific). Hence to bottom
    address of the memory we actually render into starts immediately after the
    cache.
    
    No account was taken when setting up that cache size of the alignment expected
    by the rendering code.
    
    We'll now ensure that the the cache ends, and the raster band memory starts
    on an appropriately aligned address.
