Somewhat barebones patch to implement D3DXCreateRenderToSurface for bug 24899, how much more needs to be implemented?

[Misha Koshelev]

Dear All:

Looking at d3dx9 bugs, bug 24899 requires D3DXCreateRenderToSurface.

This, somewhat barebones, patch, implements core functionality of
D3DXCreateRenderToSurface, along with a barebones ID3DXRenderToSurface
implementation.

I was wondering, in order to get this patch accepted into the wine
code base, how much more of ID3DXRenderToSurface needs to be
implemented?

Thank you
Misha
