WM Draw Methods now has a new option Automatic (default). This will

set the draw method to triple buffer or overlap depending on the
configuration. Ideally I could get all cases working well with triple
buffer but it's hard in practice. At the moment there are two cases
that use overlap instead:

* opensource ATI drives on linux
* windows software renderer

Also added a utility function to check GPU device/os/driver.
