[PATCH v3 0/5] MR5202: d3dx9: Refactor D3DXLoadSurfaceFromMemory and fix a few compressed surface bugs.
This is the first set of patches in an effort to create more generic image loading/conversion code that can eventually be shared.
-- v3: d3dx9: Preserve the contents of unaligned compressed destination surfaces. d3dx9: Split off image decompression into a helper function. d3dx9: Split D3DXLoadSurfaceFromMemory functionality into a separate function. d3dx9: Use base image pointer when decompressing source image. d3dx9/tests: Add more tests for misaligned compressed surface loading.

I have been confused about this image data for a bit. The first row is alright, but there is no way that the others are what they claim to be:
[0x1f, 0xf8] -> this sets the first and last color components to "1.0", the middle one to 0. [0xff, 0x07] -> this sets the first two (LSB to MSB) components to "1.0", last to 0. Notice also how the last row has the same color data as the first.Problem is, the tests pass and trying to "fix" the colors obviously broke the test. Turns out, this is a combination of "comment misdirection" and slight test confusion. The uncompressed texture uses D3DFMT_A8R8G8B8, which is a BGRA format - channels are sort of "reversed". So the last (MSB -> LSB) component in the expected value isn't alpha but blue. Which means the second block is purple and the third one is cyan. The last one is transparent blue. So, I'd either fix the comments to match the actual colors or (probably slightly preferable) fix the image and expected data to match the comment.
Thanks for taking the time to investigate this, hopefully I didn't waste too much of your time. The code comments should now match the test data. :) Switching between DXGI and D3DFORMATs had me confused WRT endianness.

The inefficiency of this bothered me as well, but I figured since it was a test it didn't matter so much. I've changed it in the current revision to hopefully be closer to what you were imagining.

I've gone through and changed all internal `UINT` usages into `uint32_t`, hopefully that works.

This is the only comment I'm iffy about, technically this is the `unaligned` rectangle, which is what I had named the argument initially. I felt like `exclude` made more sense WRT functionality, but I've switched back to `unaligned_rect` in the current revision.

Ah yes, I had it backwards. I think in this case I prefer this anyways; `exclude` looked a bit confusing to me, e.g. in ``` if (exclude_rect) *out_rect = *exclude_rect; ``` I agree that, in general, naming arguments by what they do rather than what they are is nicer; this one is kind of the exception. In any case, not a big deal.

Nitpicking, these could be `uint32_t` as well.

Doubled "surface".

`unsigned int` for `x` and `y`, also to match with `get_readback_color()`.

Period at the end of the `ok()` message.

One blank line is probably enough.
I only have a few nitpicky comments. I'm not approving right away to leave the chance of fixing those, but I can be convinced otherwise :smile:
