Subject: mesa: Add getters for the GL_ARB_shader_storage_buffer_object max constants
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10b5c6491f60d7cf119554f7d8e797b896707335;p=mesa.git

mesa: Add getters for the GL_ARB_shader_storage_buffer_object max constants

v2:
- Add tessellation shader constants support

v3:
- Add GLES 3.1 support.

v4:
- Move the getters to the proper place
