    vmwgfx: Don't dirty the front buffer as hw when doing a dri2copyregion from it
    
    When copying from a dri2 buffer we usually dirty it as hw, since dri has
    been rendering to it, and there can only be hw contents in the buffer.
    
    However for the real front, X has already done the dirty work for us.
    
    Also remove a glxWaitX() debug message.
    
    This should fix piglit read-front.

    vmwgfx: Add boolean flags for different rendering modes
    
    Basically we support three ways of getting data to the screen:
    1) Mixed mode: We mix presents and updates.
    2) Mixed present optimized: A version of mixed where copies to the front
       buffer end up as presents, saving a blit.
    3) 3D surface mode: We only present from a 3D surface. Software contents are
       first DMA'd to that surface.
    
    This change adds boolean flags to the saa struct to select which mode to use.
