Hi Chapman,

>1.  Only use OpenGL if you want to render 3D data like elevation data (DEM, DTED, ...) in 3D meshes.  OpenGL is awesome for 3D but slow (comparably) if you only have X,Y (2D).  It's good for cross-platform rendering, but if you're using MFC you should go with the latest native graphics device (GDI+).  In my applications I use the MDI application framework and have different Documents/Views for 2D, 3D, and raw images (rasters).

Interesting. Could tell me, please how many random 1pt lines with random 
colors  can you draw per second using GDI+ interface?

Thanks
