acron.raster

PanoramaRemap	Equirectangular panoramas resampled onto cube-map faces, headless and in float: the step between an HDRI as it is distributed (one 2:1 lat-long image) and what an image-based-lighting pipeline wants (six faces, the order and orientation TexturePool.load_cube_map uses).
RasterPainter	An anti-aliased 2D painter over an 8-bit RGBA pixel store: the canvas a HUD instrument (a minimap, a compass tape, a dial, a scope trace) draws into, since RmlUi has none.
ValueNoise	Deterministic value noise on exact 32-bit integer hashing: one seed, one world, on any machine, and bit-identical to the scalar Python twin in acron.noise (the same IEEE double arithmetic in the same order; the file is compiled with floating-point contraction off, so no FMA reorders a rounding).
