Subject: mesa: implement glTextureStorageNDEXT functions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=af60187153adce3bbd47c24abcfbaf1c403f1620;p=mesa.git

mesa: implement glTextureStorageNDEXT functions

Implement the 3 functions using the texturestorage_error() helper.
_mesa_lookup_or_create_texture is always called to make sure that 'texture'
is initialized (even if the texturestorage_error() generates an error afterwards).
