803390 - Prioritize tiles that have >= 50% on screen area

Status: RESOLVED WONTFIX

(Core :: Graphics, defect)

Description

[Benoit Girard (:BenWa)]

Current we prioritize the tiles on screen. With a phone like the Galaxy Nexus we need 3.1 by 5 (~15) tiles covering the screen. But the tiles rarely align so we frequently have to draw 5 by 6 tiles (~30 tiles). 

Tiles aligned: http://jsfiddle.net/SqDC3/2/embedded/result/
Tiles not aligned: http://jsfiddle.net/SqDC3/4/embedded/result/

This means in a lot of case we can prioritize over 80% of the screen painted by doing 1/2 the work, 1/2 the time.

I tried this and the results we're interesting. With a threshold of 80% the content came VERY quickly on taskjs but it didn't look very nice. I don't think I want to pursue this any further.

WIP in case we ever want to come back to something like this.
