This series of patches introduces a new set of structures and functions that will enable code to be re-used across various functions in d3dx9, and eventually d3dx10-d3dx11. It might be possible to split this further, but I feel like this initial set gives better context as to where things are heading.
I have a [branch](https://gitlab.winehq.org/cmcadams/wine/-/commits/WIP/d3dx-shared-s… that uses these structures and functions in d3dx10 if further context would be useful. There are a lot of changes here, but after playing around with different approaches this was the best/cleanest way I could come up with for code sharing. I'm sure there will be things I missed or potentially ways to improve this, I'm open to suggestions of course. :)
