/**
 * Native bindings to the EXT_shader_pixel_local_storage2 extension.
 * 
 * This extension builds on {@link EXTShaderPixelLocalStorage EXT_shader_pixel_local_storage} by lifting the restriction that pixel local storage is not supported when rendering to
 * multiple draw buffers.
 * 
 * Moreover, pixel local storage values are no longer lost when writing to user-defined fragment outputs, and, correspondingly, framebuffer pixel values
 * do not always become undefined when the shader writes to pixel local storage.
 * 
 * This extension adds the following capabilities:
 * 
 * 
 * support for pixel local storage in combination with multiple user-defined fragment outputs
 * support for clearing pixel local storage variables
 * support for multi-word pixel local storage variables
 *
