/**
* Native bindings to the IMG_framebuffer_downsample extension.
*
* This extension introduces the ability to attach color buffers to a framebuffer that are at a lower resolution than the framebuffer itself, with the GPU
* automatically downsampling the color attachment to fit.
*
* This can be useful for various post-process rendering techniques where it is desirable to generate downsampled images in an efficient manner, or for a
* lower resolution post-process technique.
*
* This extension exposes at least a 2 x 2 downscale. Other downsampling modes may be exposed on the system and this can be queried.
