+Helpers for drawing shader.
+
+## Todos
+
+Here are the things that needs to be implemented:
+
+- [ ] Shader compilation error reporting, e.g. to show the line number
+- [ ] Shader import from url, like shadertoy or git
+- [ ] Display shader author attribution, e.g. to respect CC-BY
+- [ ] Handle WebGL context lost by restoring the objects.
+- [ ] Multiple instances and custom canvas positions
+- [ ] Multiple programs, to be swapped like a pattern
+- [ ] Texture inputs
+- [ ] Buffer inputs, e.g. to generate a texture
