euzuro 06cbeb2f11 fix for #60 ...

conversions to/from lonlat/px need to take into account
the offset of the layersContainerDiv. 


I have introduced the following functions for converting
between layer and screen pixel values:

getLayerPxFromScreenPx() and getScreenPxFromLayerPx()

they are pretty self-explanitory.


I then renamed:

getPixelFromLonLat() and getLonLatFromPixel()

to:

getScreenPxFromLonLat() and getLonLatFroScreenmPx()

and added:

getLayerPxFromLonLat() and getLonLatFromLayerPx()


updates were made throughout the code, demos, and tests
so everything should still run smoothly.
