/**
 * Native bindings to the EXT_copy_image extension.
 * 
 * This extension enables efficient image data transfer between image objects (i.e. textures and renderbuffers) without the need to bind the objects or
 * otherwise configure the rendering pipeline.
 * 
 * This is accomplised by adding a new entry-point CopyImageSubData, which takes a named source and destination.
 * 
 * CopyImageSubData does not perform general-purpose conversions such as scaling, resizing, blending, color-space, or format conversions. It should be
 * considered to operate in a manner similar to a CPU memcpy, but using the GPU for the copy.
 * 
 * CopyImageSubData supports copies between images with different internal formats, if the formats are compatible as described in this extension.
 * 
 * CopyImageSubData also supports copying between compressed and uncompressed images if the compressed block / uncompressed texel sizes are the same.
 * 
 * Requires {@link GLES30 GLES 3.0}.
