getMaxExtent(), getMaxResolution(), and getNumZoomLevels(). They were just wrapping around the properties. better to just access the property directly. Needed to update for these removals in many different files. - Improved initResolutions() functionality. It is now I believe both thorough and complete. The only exception is that we should maybe allow a way for the user to set up resolutions[] array using only minResolution and numZoomLevels instead of only maxResolution and numZoomLevels... but I'm not really sure anyone would ever really want to use that. And at any rate, I don't know the math for how to do it. I'm sure schuyler or Dr. 5 would. Oh. for a summary of how initResolutions works, see: http://trac.openlayers.org/wiki/SettingZoomLevels - Move getResolution(), initResolutions() out of HTTPRequest and into Layer. On thinking this through (and trying to write documentation), I realized that the real, true, GENERIC case for a layer will be using this awesome resolutions[] array that allows for setting number of zoom levels, default max resolutions, special scale arrays, etc. - Updated code for getZoomForExtent() to work with resolutions[] array, instead of using the the log 2 equation. - Move standard getZoomForExtent() and getExtent() out of Grid and into Layer. Like above, there is no reason for these methods to be found so far down in the food chain. They are part of the generic calculations for generic layers, so they belong in Layer. git-svn-id: http://svn.openlayers.org/trunk/openlayers@1379 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
