/**
* Native bindings to the EXT_clear_texture extension.
*
* Texture objects are fundamental to the operation of OpenGL. They are used as a source for texture sampling and destination for rendering as well as
* being accessed in shaders for image load/store operations It is also possible to invalidate the contents of a texture. It is currently only possible to
* set texture image data to known values by uploading some or all of a image array from application memory or by attaching it to a framebuffer object and
* using the {@code Clear} or {@code ClearBuffer} commands.
*
* Both uploading initial texture data and clearing by attaching to a framebuffer have potential disadvantages when one simply wants to initialize texture
* data to a known value. Uploading initial data requires the application to allocate a (potentially large) chunk of memory and transferring that to the
* GL. This can be a costly operation both in terms of memory bandwidth and power usage. Alternatively, attaching a texture level to a framebuffer to
* clear it may not be possible if the texture format isn't supported for rendering, or even if it is, attaching the image to a framebuffer object may
* cause the texture to be allocated in certain types of memory, which it may otherwise not need to be placed in.
*
* This extension solves these problems by providing a mechanism whereby the contents of a texture image array can be set to known values by using the
* {@link #glClearTexImageEXT ClearTexImageEXT} or {@link #glClearTexSubImageEXT ClearTexSubImageEXT} commands. These commands can also be useful for initializing an image that will be used for atomic shader
* operations.
*
* Requires {@link GLES31 GLES 3.1}.
