/**
* Native bindings to the EXT_texture_storage extension.
*
* The texture image specification commands in OpenGL allow each level to be separately specified with different sizes, formats, types and so on, and only
* imposes consistency checks at draw time. This adds overhead for implementations.
*
* This extension provides a mechanism for specifying the entire structure of a texture in a single call, allowing certain consistency checks and memory
* allocations to be done up front. Once specified, the format and dimensions of the image array become immutable, to simplify completeness checks in the
* implementation.
*
* When using this extension, it is no longer possible to supply texture data using TexImage*. Instead, data can be uploaded using TexSubImage*, or
* produced by other means (such as render-to-texture, mipmap generation, or rendering to a sibling EGLImage).
*
* This extension has complicated interactions with other extensions. The goal of most of these interactions is to ensure that a texture is always mipmap
* complete (and cube complete for cubemap textures).
*
* Requires {@link GLES20 GLES 2.0}.
