If you're changing these anyway, LPCSTR is a broken way of saying
"const char *".

I generally prefer %#x for things like file_format, but don't care
particularly strongly. For src_rect you should use %s and
wine_dbgstr_rect(). I don't care much for the "relay" suffix, but I
suppose half the existing code has it as well.

The HEAP_ZERO_MEMORY flag is useless, you're immediately going to
overwrite all the memory afterwards. Sadly the existing d3dx9 code
isn't a very good example here either.
