metal: only 4 (instead of 5) vertices are needed to draw rectangles and textures, and only 3 (instead of 5) vertices are needed to cover the screen for the 'full-screen quad' when clearing.

Defer getting the next drawable until we actually start rendering
...
This works better for games where there may be a bunch of simulation logic that needs to be run before the next rendering pass, and prevents blocking if the next drawable is busy.

Initial shot at a renderer target for Apple's Metal API.
...
This isn't complete, but is enough to run testsprite2. It's currently
Mac-only; with a little work to figure out how to properly glue in a Metal
layer to a UIView, this will likely work on iOS, too.
This is only wired up to the configure script right now, and disabled by
default. CMake and Xcode still need their bits filled in as appropriate.
