Implement vertex shading
This adds support in all backends, but the Compatibility renderer works the best. Mobile and Forward+ can only support one directional light shader (the first in the tree) While the Compatibility renderer supports any number of shadows. Co-authored-by: Clay John <claynjohn@gmail.com>

If [code]true[/code], forces vertex shading for all rendering. This can increase performance a lot, but also reduces quality immensely. Can be used to optimize performance on low-end mobile devices.
