* Don't call context.getResources() redundantly when unnecessary;
similarly for Resources.getCompatibilityInfo()
* During bitmap creation, don't bother clearing to 0: it's unnecessary
because now that the raw bits are stored in a VM-side byte array, it
was cleared at initialization time. Also, don't use the sanity-
checking public entry point to erase to a color, because we know
that we're by definition in a "legal" path to erase to the initial
contents and don't need to incur the overhead of the (inappropriate)
sanity checking.
