Revision History

added support for generating high-resolution images
fixed issue that was causing OpenGL rendering to be performed in software under Windows Vista/7
added functionality for creating bar charts
abundance information specified in sequence files can now be used to create quantitative pie or bar charts
continuous colours assigned to location sites can now be propagated onto an attached tree
labels (which are slow to render) are now automatically hidden when interacting with the viewport in order to improve responsiveness
visual properties of trees have been improved by adding support for thick branches, optional borders, and independent control over the size of leaf and internal nodes
added support for optional border around location markers
all properties dialogs have been changed to a modeless, stay-on-top style in order to facilitate interactively changing properties
font used to render labels can now be set in the Settings->Font Settings dialog
reduced loading time and memory requirements for maps
the maximum terrain resolution can now be set in the Studies Properties Dialog (this can be helpful on low memory systems)
double clicking on a chart now bring up the Locations Properties Dialog instead of the Location Set Properties dialog
minor UI design improvements to the majority of the layer dialog boxes

changed licensing from Creative Commons Attribution - Share Alike 3.0 to GPL 3.0 or later
initial interface to MOA database
Locations tab now shows a legend indicating the marker assigned to each location site
location site labels can now be set to either 'billboard' or 'dynamic' style
added View->Widgets menu items to show or hide all widgets
modified layer names are now reflected in the layer tree control
removed menu items associated with creating and saving studies (this functionality is now scheduled for v2.0)
added functionality to remove custom labels (right-click popup menu)
layers can now only be hidden through the check boxes in the layer tree control (this ensures that the visibility of a layer is allows indicated by the check box)
fixed bug introduced in v1.06 that prevented moving labels
fixed bug causing location site labels to transition from a 'billboard' to 'dynamic' style when moved

added support for 3 or 4-channel GeoTIFF images
improved handling of OpenGL textures to support high-resolution GeoTIFF images
significant improvements to rendering speed under Microsoft Windows Vista and 7 (and possibly XP and OSX although these rendered quickly before)
changed default projection to plate carrée (equirectangular) projection as it can properly handle all maps
more efficient handling of main memory and GPU memory
fixed visual artifacts in compass widget under Microsoft Windows Vista and 7
fixed (hopefully!) bug which occasionally caused a map to fail to appear when loaded
modified handling of log file so it works under Microsoft Windows Vista and 7
added additional log statements to help in debugging end users
fixed bug in Map Properties dialog which was preventing modification to a map's colour map

major bug fixes to OSX version:
- sequences can now be loaded
- layers can now be selected/unselected
- map level-of-detail is now set properly
- numerous cosmetic improvements
implemented dialog which allows user to specify which sequences are active
update dataHelper class to provide functions for placing sequences in the active set
added tree popup menu item to allow the order of points to be reversed
minor bug fixes to tree projection code
various minor bug fixes

added general purpose, user labels
Several extensions to the GenGIS Python API:
- functions to obtain the width and height of the OpenGL Viewport.
- functions for manipulating pie charts
- functions for drawing markers, lines, and labels
- several minor additions
trees of high dimensionality (> 9) can not be optimally laid out for computational reasons, so a heuristic layout is used
fixed memory leak related to incorrect use of Font class
shape maps now save any user modifications
various minor bug fixes

background colour of GenGIS Viewport can be set by user in Study Properties Dialog
improved rendering quality of labels
labels associated with location sites can now be interactively positioned
the contents of the GenGIS Viewport can now be saved as a PNG file using File->Save image as...
added Python function convertGeoCoord() which allows geographic coordinates to be converted into GenGIS Viewport coordinates
added Python function addLine() which allows a user defined line to be rendered in the GenGIS Viewport
added Python function openTree() which allows tree files to be loaded
extended movieHelper.py to include setCameraParam() function
added warning message regarding optimization of leaf nodes for trees with degree > 9
various minor bug fixes
