The settings above would set tile size to (256, 256) and add 25ms delay between constructing individual tiles. The settings would try to cache an area 1.5x width and 1.5x height of the current viewport (centered to the viewport) with tiles and would drop tiles after they are outside an area 2x the width and 2.5x the height of the viewport. 237795 11 kenneth 2010-06-14 06:35:07 -0700 should we document our private api on the wiki? 57321 2010-05-28 06:13:38 -0700 2010-05-28 06:15:48 -0700 trivial webcore
