We also redefine the path parameters as VString instead of const char*, so that we can pass them through to VPlatformAPI low level functions (on Windows these need to denormalize the path string and widen it to UTF-16 for use with Win32 wide string APIs that can handle Unicode; contrast with Unix/Mac which can take our existing UTF-8 char strings).
