 /*  These return the correct subclass of blitter for their device config.
 
     Currently, they make the following assumptions about the state of the
     paint:
 
     1. If there is an xfermode, there will also be a shader
     2. If there is a colorfilter, there will be a shader that itself handles
        calling the filter, so the blitter can always ignore the colorfilter obj
 
     These pre-conditions must be handled by the caller, in our case
