Summary of changes
SetScaleBar, SetLegend, SetCopyright and other new functions allow scale bars, legends (map keys) and copyright notices to be added to the map easily, and to be displayed properly when using hardware graphics acceleration.
Boxed labels for point objects can now optionally have small triangular pointers which indicate the exact position of the point object.
The makemap tool can now write multiple output maps from the same set of input data; any number of pairs of extent and output file name can be provided.
There are geodesic functions (straight-line distance between two points, and the azimuth functions) which use accurate functions based on the WGS84 ellipsoid, not spherical approximations. The spherical approximation is still used internally where speed is more important than accuracy.
The Android API now mostly uses enums, not integer constants.
