picogl.backend.modern.core.shader.context

OpenGL context checks for shader compile/bind (Qt + headless).

Functions

clear_gl_errors(→ None)	Drain pending gl errors so the next call's status is meaningful.
gl_context_available(→ bool)	True when a gl context is current and glGetString(GL_VERSION) works.
require_gl_context(→ None)
program_is_valid(→ bool)
