picogl.backend.texture

Module provides utility functions and a class for managing OpenGL textures.

This module contains context managers for handling texture bindings, utility functions for creating procedural textures, and the TextureManager class for managing and reloading textures. It integrates with OpenGL through a backend driver, providing streamlined texture handling and fallback behavior.
