Mostly as a "while you're at it", we usually zero-out object allocations, so probably this would be better as a calloc().

This one should probably be replaced by a calloc(). Additional upside, you should be able to drop the memset below.

I guess I have to point out that this could fail, after mentioning the same in the d3drm MR :sweat_smile: 

Like there, you can assign the result to a different variable and update ret->buffer only when it's non-NULL.

No big deal, but for this one there is really no need to multiply by sizeof(char).

Using calloc for overflow checking seems like a good idea for both of those.

As usual, it's an object initialization so we want to zero the memory (calloc).

It's a stub and obviously it's a preexisting issue but still...

Nothing major, except for the sprite issue (which doesn't make the tests fail but it causes a bunch of err: to be printed out - I'll probably send a followup patch to handle sprite rendering failures in ID3DXFontImpl_DrawTextW()).

Please change the subject prefix to just "d3dx9:" when resending.
