internalformat

A GLenum specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format).

pname

A GLenum specifying the type of information to query. Possible values:

gl.SAMPLES

Returns a Int32Array containing sample counts supported for internalformat in descending order.
