Yes i think that was the main thing i was thinking as well, I just didn't realise it had a name "front-to-back" ;-)

So basically, for each line:

- calculate the tile values for Plane A
- Render Plane A high tiles
- calculate the tile values for Plane B which are still visible
- Render Plane B high tiles clipping to uncovered pixels
- Render Plane A low tiles clipping to uncovered pixels
- Render Plane B low tiles clipping to uncovered pixels

Making sure to skip completely blank tiles

Do you reckon that's pretty much as fast as it gets?

You learn something old everyday...
