/**
* Native bindings to the EXT_texture_view extension.
*
* This extension allows a texture's data store to be "viewed" in multiple ways, either reinterpreting the data format/type as a different format/ type
* with the same element size, or by clamping the mipmap level range or array slice range.
*
* The goals of this extension are to avoid having these alternate views become shared mutable containers of shared mutable objects, and to add the views
* to the API in a minimally invasive way.
*
* No new object types are added. Conceptually, a texture object is split into the following parts:
*
*
* - A data store holding texel data.
* - State describing which portions of the data store to use, and how to interpret the data elements.
* - An embedded sampler object.
* - Various other texture parameters.
*
*
* With this extension, multiple textures can share a data store and have different state describing which portions of the data store to use and how to
* interpret the data elements. The data store is refcounted and not destroyed until the last texture sharing it is deleted.
*
* This extension leverages the concept of an "immutable texture". Views can only be created of textures created with TexStorage*.
*
* Requires {@link GLES30 GLES 3.0}.
