<br><font size=2 face="sans-serif">I am doing a deep dive into the openlayers
code in an attempt to further understand how tile loading is implemented
in order to fix some issues I am having with a custom implementation. One
thing that I am having trouble figuring out is whether all of the tiles
are loaded for each zoom level right away when the zoom happens of if there
is a way to get OpenLayers to only load the visible portion of the tiles
plus a buffer (with further loading being triggered when the user pans
into the buffer). From what I can tell tile loading (addTile) is
only called by initGriddedTiles, and only when the forceReTile boolean
is triggered by a zoom or by a pan that goes completely outside of the
layer boundaries?</font>
