Every .edds in the game paks now reads and decodes (29,139 files, 0 failures). The last two failures were:

• system/textures/CurlNoise_F16.edds: FourCC field holds 112, the numeric D3DFMT_G16R16F.
• system/textures/PP/base16_32x32_LUT.edds: a 32x32x32 volume texture (DDSCAPS2_VOLUME), FourCC field 36 (D3DFMT_A16B16G16R16). It's an identity color grading LUT: x is red, y green, the slice blue.

Changes

• FourCCEnum: numeric D3DFMT_* codes 36 and 110 to 116, so these headers read.
• EddsFormat::Rg16Float and EddsFormat::Rgba16, from the FourCC codes or the DX10 header (R16G16_FLOAT, R16G16B16A16_UNORM). For the 8 bit output RG16F is clamped to 0..=1 like BC6H (negative values become 0, RawEdds keeps the stored values), RGBA16 is rounded.
• Volume textures: new Mipmap::depth (1 for 2D textures) that halves with the mipmaps. Slices are decoded one by one and stored one after another, so a decoded volume mipmap reads as a width x height * depth image.

Mipmap gets a public field, so code that builds a Mipmap by hand needs to set depth.

The game's only volume texture has a single mip, so the depth halving across mip levels follows the DDS convention and is covered by synthetic tests only.

Tests

• Synthetic: both formats from FourCC and DX10 headers, a volume mip chain, a too short volume, a block compressed volume with cropped blocks.
• Game files: both textures added to e-test-data-part-1.7z, checked by sample texels and checksums.
