The following functions should be aligned with regards to validating bound VAOs (if needed), doing implicit clears, and marking the canvas as changed.

- WebGLRenderingContextBase::drawElements 
- WebGLRenderingContextBase::drawArrays
- WebGLRenderingContextBase::drawElementsInstanced
- WebGLRenderingContextBase::drawArraysInstanced
