/**
* Native bindings to the NV_conservative_raster extension.
*
* This extension adds a "conservative" rasterization mode where any pixel that is partially covered, even if no sample location is covered, is treated as
* fully covered and a corresponding fragment will be shaded.
*
* A new control is also added to modify window coordinate snapping precision.
*
* These controls can be used to implement "binning" to a low-resolution render target, for example to determine which tiles of a sparse texture need to
* be populated. An app can construct a framebuffer where there is one pixel per tile in the sparse texture, and adjust the number of subpixel bits such
* that snapping occurs to the same effective grid as when rendering to the sparse texture. Then triangles should cover (at least) the same pixels in the
* low-res framebuffer as they do tiles in the sparse texture.
*
* Requires {@link GLES20 GLES 2.0}.
