.. py:function:: compile_shaders(vertex_src: str, fragment_src: str, shader_name: Optional[str]) -> Optional[picogl.backend.modern.core.shader.program.ShaderProgram]

   Compiles and links a vertex + fragment shader_manager.current_shader_program shader_program using Qt's OpenGL API.

   :param shader_name: str
   :param vertex_src: Vertex shader_manager.current_shader_program GLSL code.
   :param fragment_src: Fragment shader_manager.current_shader_program GLSL code.
   :return: Linked PicoGLShader or None on failure.
