 Priority:  major    |   Milestone:  6.3.0

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

 User may expect, that all points are drawn with same distances between
 them during pan.
