DXT DDS textures upload the file's own mip levels like 40250 CGraphicImageTexture::CreateDDSTexture (max(1, dwMipMapCount), level i read at sum(dwLinearSize>>2k), Copy of dwLinearSize>>2i bytes) instead of a regenerated chain. Non-DDS images keep the D3DX_DEFAULT full chain and mem: textures get one level. The invented is_ui_tex no-mip rule (icon/, ui/, locale/, <=128px) is deleted. dxt_decode_test is registered in ctest with mip-level cases. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Divergence: without DDSD_MIPMAPCOUNT, or with DDSD_PITCH, 40250 creates the extra levels uninitialised; here that is one level. IsLowTextureMemory's uTexBias level skip is not applied (the port's ms_isLowTextureMemory is false). The far-terrain look NEEDS_LIVE."

The invented is_ui_tex rule (no mips for icon/, ui/, locale/ and textures <=128px) was removed. Memory textures (mem:, 40250 CreateTexture levels=1) get one level.
