layers: Don't pre-query surface attributes during creation
Browse files Browse the repository at this point in the history 
Some of the calls to get surface capabilities, formats or
presentation modes are very slow in some implementations.
Revert back to caching results made by the application, but
store them in SURFACE_STATE rather than PHYSICAL_DEVICE_STATE.
The original code assumed that the same results would apply
to all surfaces, which doesn't appear to be true.
