Now with Delaunay triangulation...

Contains animation code, axes, docking windows, locator form...

Large number of changes in this one:

+ Added benchmarking tool

* Removed JVCL dependancy

+ Added export module
* Much improved colour scale (all types, all modes)

Now with a fancy import module as well as colour scale legend.

Note the legend is not complete - it only works for the data points .clr and is missing some options. The colour scale is not activated yet for surfer or arcinfo grids.

The glData CVS is now online!!
Laid out with the following top level modules:

built - readme, nsis script, sample and aux files
comps - required components (Import/Export)
dcus - for generating dcus (but not in repository)
project - contains dpr for Delphi 7
source - source tree

Have fun.
