KaMap needs to reimplement initTiles because it uses 0-based indexing instead of lower-left corner indexing, which means that we need to have the tile.draw method also modified here to use this.alpha, and also add the options hash as a param. We should probably move resolution/units into the options param too?

We round these values to four decimale places: This saves us on rounding errors on the client-side, which could theoretically increase our cache size when we hit them, and in the case of the left/top values, this also makes sure that we get the closest pixel value, not the integer of it -- this is important when we get around to requesting the tiles, since otherwise we end up a pixel off, and then we don't get our images back.

Convert KaMap and WorldWind to be isBaseLayers, and change FullExtent to MaxExtent.

KaMap can't round. It works fine for degrees, but when you're working in inches, feet, meters, the rounding errors become quite significant.

Round the scale value. KaMap rounds internally, so adding extra precision here only breaks client-side caching.

KaMap layer now sublasses initTiles, to implement the kamap 0-based tiling scheme instead of the OpenLayers/WW -180,-90 method. This means that there are no longer any restrictions on using ka-Map with other layers! woohoo! You can use ka-map on top of WorldWind, or with another ka-map layer, even if it has differently sized tiles. yay!

OpenLayers.Layer.KaMap is now working much better. The TIGER example which was just a hack before is now working properly, and there's an actual scale calculation being performed based on params passed into the constructor of 'units' and 'resolution', both of which are determined by the mapfile. The only limitation yet to be tackled is that maxResolution on the map must split the map up such that 0,0 is a tile corner. This requires subclassing more (or perhaps all) of the Layer.Grid functions, so I'm off to do that now.

More work on KaMap layer. This TIGER demo looks good, but it's really broken underneath.

OpenLayers.Layer.KaMap, for displaying KaMap-tiles in OpenLayers. Currently specific to the example -- needs work on determining 'scale' from resolution. possibly just simple math. I'm not sure yet.
