PNG/JPG decode через libavcodec (системный decoder), conversion в RGBA8 через swscale, upload в pitched CUDA buffer, blit через Alpha_Blit_RGBA_Y/UV (те же kernels что text). Icon cache — shared by name (одна и та же иконка для нескольких overlays = один GPU atlas). Lifecycle: load on first use, free в uninit. Path resolution: <icon_dir>/<name> + try .png/.jpg extensions: /var/lib/cuda-grid/icons (default) /opt/cuda-grid/icons (fallback) + abs path supported Options: icon_dir= — overrides default search paths Wire format: add_overlay <id> icon x=.. y=.. icon_name=domofon opacity=200 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
