impostor_from_baked / impostor_refill read a bundle of two DX10 .dds (albedo, normal: BC7_UNORM, every
level) through tex_load_dds_at and gpu_tex_compressed - no gpu_tex_mips - and check each is the
impostor's size; sampled as a painted atlas is (clamped, no anisotropy). No BC on the GPU, or a bake
that does not fit, and the caller paints RGBA8 and makes mips as before; the fog re-open reads the BC7
file again. The handles and every draw are unchanged. Compile-only: nothing run.

ludic.lab: lab_png_write / lab_png_write_from (raw 8-bit, 1-4 channels, stored deflate) in png_write.ludic,
importable alone with its own LabPngState; png_convert.ludic's previews of float textures (R32F min..max,
RG16F x255, HDR x/(1+x) + sRGB); lab_ppm_to_png on the same encoder.
render3d: bake_load.ludic - impostor_from_baked / impostor_source / impostor_refill (a fog re-open reads
the bake), sky_baked_in and sky_precompute trying the bake at the start yaw (sky_compute is the
convolution, and sky_ibl_bytes always uses it), carpet_from_baked / carpet_bytes / carpet_finish,
bake_part_count / _len / _off. Compile-only: nothing run.
