Note that I dropped quite a few things related to CFLAGS:
- the -mfsrra / -mfsca discovery was clean cmake and could have stayed;
but kos-cc already passes those flags, so -ffast-math is enough to
enable the FSRRA / FSCA instructions.
- -fomit-frame-pointer is also a default option of KOS.
- -fexpensive-optimizations, -finline-functions and -fstrict-aliasing
were redundant as they are enabled by the optimization level
specified.
- -ffp-contract=fast is the default when using GNU C, which we are here.

The test could inherit a previously uploaded NPOT/strided texture from an earlier test, causing GL_REPEAT to be rejected before the POT upload occurred. Upload the POT texture before setting repeat wrap so the test verifies that POT textures still allow repeat wrapping.
Replaced GL_KOS_texture_stride with GL_KOS_texture_non_power_of_two
Removed the explicit texture parameter and made supported NPOT GL_TEXTURE_2D textures automatically use the PVR strided backend
Added clamp-only validation and retained the existing restrictions around mipmaps, wrapping, and unsupported formats
The underlying PVR strided implementation remains the same. GL_NV_texture_rectangle can be considered as a future follow-up.
Add a Dreamcast GLdc sample that loads a .dt texture from romdisk.
This adds a new nehe06_dt sample based on the existing NeHe cube demo, but loading a Dreamcast .dt texture directly from romdisk instead of the older texture formats.
Changes:
- add samples/nehe06_dt/main.c
- add samples/nehe06_dt/romdisk/NeHe.dt
- register the sample in CMakeLists.txt
The sample is useful for checking GLdc texture loading with Dreamcast-native .dt assets and for comparing the output against the source artwork on hardware.
moved MIRROR bits into bits 2 and 3 of what used to be `uv_clamp` member of TextureObject
renamed `uv_clamp` member to `uv_wrap`
updated and commented code accessing `uv_wrap` for both clamp and mirror settings
