/**
 * Native bindings to the NV_memory_attachment extension.
 * 
 * This extension extends the memory objects introduced with {@link EXTMemoryObject EXT_memory_object} to allow existing textures and buffers to be migrated to an
 * imported memory allocation. The primary use-case of this extension is plug-in development where resource management (creation, deletion, sizing etc.)
 * is handled by inaccessible host application code.
 * 
 * Requires {@link EXTMemoryObject EXT_memory_object} and {@link ARBTextureStorage ARB_texture_storage} or a version of OpenGL that incorporates it.
