1In commands, gather up option values first, and check for errors. If there 2 is an error in an option specification, return before messing with the 3 object. Otherwise, go ahead and mess with the object. 4Evaluate maxlon and minlon correctly when reading in lat-lons (polar regions), 5 or provide for explicit input of maxlon and minlon (which could be set to 6 bogus). 7Add flag to GeoLnArrToMap that does not worry about segments if just drawing 8 points. 9Create C functions for arithmetic on angles that check for "overflow." 10Restore Sinusoidal projection (or install some other global equal area 11 projection). 12Option to make geomap::lnarr fmbin and fmxdr read double precision. 13Decide if Add*Task and Cnx*Task functions should return success code instead of 14 void. 15Retire gaz@tkgeomap.org 16Optimize the calculations that use spherical trigonometry. 17Make geolinearray and maplinearray structures resemble each other. If 18projection is cylindrical equidistant, skip maplinearray transformation to 19save memory. 20
