[Vesa Solonen <vsolonen@...>]

I just wanted to point out that sysprof by Søren Sandmann seems very 
useful for finding bottlenecs in code. It is available in Ubuntu repos 
too. Any experiences or comments from anyone? Zoom and redraw speedups 
are something I'm aiming at. Pcbnew seems to spend most of the time in 
ZONE_CONTAINER::DrawFilledArea, TRACK::Draw and MODULE::Draw (19/17/14 
out of 54). Background dot grid uses quite a lot of callbacks too.

For background, how about dropping exactness in screen measures and always 
fit the grid to even pixel count? Then wxBrush coud be used for drawing 
and the would probably speed up alot compared to single pixel draw call.
