Description
After panning around in wxgrass map window, some points are drawn shifted away from their location.
Steps to reproduce:
1) Add some line layer in wxgrass (i.e. roads from spearfish6);
2) Add some point layer (i.e. bugsites);
3) Take a screenshot;
4) Pan map;
5) Take a screenshot;
6) In Gimp (or any other raster manipulation soft) combine both screenshots in such way, that line layer features match;
7) Examine all point features and notice unsharp points - those are not drawn in same place as in first screenshot.
User may expect, that all points are drawn with same distances between them during pan.

Can you still reproduce this bug with current wxGUI?

This ticket is over a year and a half old and seems inactive. The display system has been regularly improved over this time. I just replicated the steps above on the current 6.4 (compiled a couple days ago) on a Mac and there is no shift. All vectors line up perfectly as far as I can see.
I'm changing this to fixed. If someone still has a problem, we can change it back.

Green - OK; red- shifted points.
