874c9f49d5 b=455513; add optional flag to allow converting a DDB to a DIB internally, if the surface is every used as a source; r=jmuizelaar
If a DDB is used as a source for an operation that can't be handled
natively by GDI, we end up needing to take a really slow path (creating a
temporary surface for acquire_source) for each operation.  If we convert
the DDB to a DIB, we then end up having a real image buffer and can hand
things off to pixman directly.

This isn't the default mode because I'm not sure if there are cases where a
DDB is explicitly needed (e.g. for printing), and it would change
current cairo behaviour.  It might become the default at some point in the
future.
