picogl.backend.gl.task.gl_init
==============================

.. py:module:: picogl.backend.gl.task.gl_init

.. autoapi-nested-parse::

   Module for executing sequences of OpenGL tasks in a specified order.

   This module provides a utility function to execute a list of OpenGL-related
   tasks using a provided backend. Each task is represented by a tuple that includes
   an optional message to log and a callable representing the task to be executed.

   Classes and Functions:
   - execute_gl_tasks: Executes a list of OpenGL task tuples, optionally logging the progress
     or providing step callbacks.

Module Contents
---------------

.. py:function:: set_clear_color_only(backend: picogl.backend.gl.backend.GLBackend, color: tuple[float, float, float, float]) -> None

   Set the clear color without clearing (safe before the default FBO is ready).


.. py:function:: clear_to_color(backend: picogl.backend.gl.backend.GLBackend, color: tuple[float, float, float, float]) -> None

   Apply a clear color and clear the color/depth buffers.
