     * Specifies a boundary between passes when reading existing framebuffer data from fragment shaders via the {@code gl_LastFragData} built-in variable.
     * Previous framebuffer object writes regardless of the mechanism (including clears, blits and primitive rendering) are guaranteed to be visible to
     * subsequent fragment shader invocations that read from the framebuffer once {@code FramebufferFetchBarrierEXT} is executed.
     * 
     * If {@code EXT_shader_framebuffer_fetch} is also supported: Because the implementation guarantees coherency of framebuffer reads and writes for color
     * outputs not explicitly marked with the noncoherent layout qualifier, calling the {@code FramebufferFetchBarrierEXT} command is not required unless the
     * application wishes to manage memory ordering of framebuffer reads and writes explicitly, which may provide better performance on some implementations
     * in cases where rendering can be split into multiple passes with non-self-overlapping geometry.
