As a technical demo they're great. In practice though, I wouldn't recommend using these techniques because:
- Many are completely broken in FF
- Crashed my FF (19.0.2) and strangely sent my GPU fan into overdrive
- These techniques hurt performance badly. In the case of gradients
the browser has to first generate the bitmaps
from the gradient definitions, apply any clipping/masks
and then composite any other overlaying elements.
This is far more taxing than simply grabbing a
bitmap and painting into a region.
