Geomap enhancements (#1767)

Browse Source 
* Increase Geomap zoom-in ability
* Use floating point for current position
* Show grid squares when zoomed in too much for map
* Zoom in fast after exceeding map resolution & clean up redundant code
* Revert order of functions to make it easier to review
* Changed grid color for better contrast with markers
* Optimizations
* Set x_pos/x_pos to center pixel versus upper left corner
* Show more distant planes when zoomed out
* Correct pixel offset when zooming in
* Fix oops in x_pos/y_pos centering change
* Wrapping support for lat/lon fields
* Wrapping support (for Geomap lat/lon fields)
* Handle wrapping for negative lat/lon
