Mupen-owned D2D brushes #586
Description
Rationale
Having Lua-owned D2D brushes was a terrible idea. They're easy to leak, caching them involves Lua-side tables and lookups... Terrible.
Proposal Summary
Mupen should own D2D brushes and lend lightuserdata to Lua.

Technical Considerations
This change sounds like it's breaking, but it doesn't have to be. We can just stub out d2d.delete_brush.
Is it worth doing it like that, or should we break the D2D API?
