Nothing made a framebuffer with additional colour attachments, so they go from AbstractFramebuffer, CreateFramebuffer and every backend, and FramebufferState's additional_color_attachment_count (always 0) with them: render passes, views, clears, RTVs and blending are for one colour attachment, in fixed arrays rather than vectors. Vulkan samplers are kept in an open-addressed table grown by doubling and render passes in a fixed array, so looking one up never allocates. Play allocations on the core's thread: 62 to 58.
