Add facility for debugging webgl calls

It would be good to have a possibility to register a callback for all webgl errors.
Khronos describes how that can be done: https://www.khronos.org/webgl/wiki/Debugging
They have a repo containing helpers https://github.com/KhronosGroup/WebGLDeveloperTools
Someone also put it on npm: https://github.com/vorg/webgl-debug

We could try to integrate their code, or write something similar ourselves.
We should try if Khronos' approach supports webgl2.

Start with the Khronos WebGL Debugging documentation and compare the WebGLDeveloperTools and vorg/webgl-debug repositories. Determine whether the described callback approach supports WebGL2, then identify how it could fit into this TypeScript WebGL framework. Done means a defined integration approach for registering callbacks on WebGL errors.
