Issues

1) Does VI need a way to query for compatibility between a particular physical device (and queue family?) and a specific VI display?

RESOLVED: No. It is currently always assumed that the device and display will always be compatible.

2) VkViSurfaceCreateInfoNN::pWindow is intended to store an nn::vi::NativeWindowHandle, but its declared type is a bare void* to store the window handle. Why the discrepancy?

RESOLVED: It is for C compatibility. The definition for the VI native window handle type is defined inside the nn::vi C++ namespace. This prevents its use in C source files. nn::vi::NativeWindowHandle is always defined to be void*, so this extension uses void* to match.
