Fix several Dreamcast hardware regressions found while testing real PVR behavior. - Upload the default white texture through the platform texture loader instead of memcpy directly into PVR texture memory. - Add GPUTextureLoad so SH4 uses pvr_txr_load while the software backend keeps memcpy behavior. - Track scissor/userclip application per polygon list and invalidate scissor state at buffer swap. - Submit queued geometry before USERCLIP/header transitions in the SH4 submit path. - Remove the stale packed 4bpp source-size double-halving in glTexImage2D. - Add texture regression coverage for packed 4bpp, unpack row length, compressed palette4 forwarding, and 8bpp-to-4bpp packing. - Update the scissor sample and add polygon_compare as a small hardware comparison sample. Verified: - make -C dcbuild gldc_tests scissor polygon_compare - scissor sample on Dreamcast hardware - polygon_compare sample on Dreamcast hardware - existing strided texture sample on Dreamcast hardware |
