Graphics performance on Windows and Mac #170

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The time to draw many points or polygons in any view is significantly slower on 
OSX and Windows than in Linux.  I have done a fair bit of research into this 
already and have some ideas to improve performance.  More details to follow.

The full solution to this problem will require using wxDC for Linux and Windows 
and wxGraphicsContext for OSX.  For release 1.2, any new views will use this 
solution, but older existing views will get this performance improvement until 
they are rewritten.  This will not likely be finished until at least version 
1.4 since we don't want to spend all our time improving old features rather 
than working on new features.
