"exposé"), presentation of all workspaces… Not quite. They use GLX_EXT_texture_from_pixmap, which initially was only available with available for indirect contexts (and thus AIGLX was needed). With DRI2 (and a graphics memory manager in the kernel), tfp (and thus GL compositors) is also possible with direct GL contexts.
