* Format: check pattern sizes on load (#3478) A .pcraft pattern's width/height came straight from the manifest, so a 1 KB file could declare a 65535x65535 pattern without tiles; painting it allocated width*height*16 bytes (abort) and the engine's u32 size math overflowed. - format: reject patterns 0 px on a side (Corrupt) or above the PSD reader's 30 000 px edge (LimitExceeded). - doc: Pattern::pixel_count / is_paintable with MAX_PAINT_PIXELS (2^26, a 1 GiB f32 RGBA working copy). - compose/gpu: patterns too large to paint paint nothing instead of allocating (Tile::new_in, pattern_rgba, PreparedPatterns, GPU plan). - engine: brush.texturePattern refuses them; average_color uses u64 math and a bounded corner.
