Changes in GeoZui3D 3.3

These are the changes in GeoZui3D version 3.3, since the release of version 3.2.

Interface

New, less intrusive 3D rotation widgets.
Widgets now default to having horizontal and vertical scales enabled.
Work-around added to allow GeoZui3D to be used with certain graphics drivers that contain errors in their OpenGL implementation. While this fixes some problems (such as not updating when a GUTM is loaded), it may not fix others (such as waiting a long time for responding to certain mouse events). We still recommend downloading the latest drivers from your graphics card vendor if difficulties persist.
The limited navigation available for the keyboard is now documented in the "Keyboard Navigation" section of the online documentation.

The Geographic Data Points (.gdp) format now supports a COLUMNS option for the SIZE of each point. When combined with the new unit-size glyphs for this format, the allows a user to use points to represent attributes with spatial characteristics. The new unit-size glyphs are UCU, UCY, and USP, for unit-cube (width of 2m), unit-cylinder (radius of 1m), and unit-sphere (radius of 1m), respectively.
Geographic Data Lines (.gdl) files no longer crash GeoZui3D when tubes are turned off.
The shading of GUTM's has been modified slightly to better reflect sudden changes in height.

Many of the scripting features available in GeoZui3D are now documented. See the Scripting Interface section of the online documentation for details.
Supports "-f filename" option on the command line for starting GeoZui3D from an outside process or from a shortcut. On Windows systems, use of the -f option automatically maximizes the main window before the specified file is opened.
Redesigned recording mechanism. While this function is still in development, it should provide for more robust recording and playback than the previous mechanism, and be more backward compatible in the future. Any recordings made with past versions of GeoZui3D will not work with the current, or any future versions (due mostly to the changes in the widgets, and the fact that the old recording mechanism depended solely upon recording mouse and keyboard input). The new mechanism records more information, making future interface changes less likely to disrupt recorded scripts. Additional information about recording can be found in the following sections of the online documentation: the Tools Menu section, and the Selected Global Procedures and Selected Togl Subcommands sections.
