gpu.framebuffers

Class description
This symbol represents the framebuffer supplied by the window system to store the contents of the window on screen. Since this framebuffer is managed by the window system, it cannot have its attachments modified or resized; however, it is still a valid target for rendering, copying via copy-framebuffer, clearing via clear-framebuffer, and reading via read-framebuffer.
