Windows only: White dots on the summary view

[laksono]

Procedure:

• Open a database with big traces (lot of threads or MPI processes).
• Activate a summary view
• Sometimes there are white dots

On Linux, the problem doesn't occur since the colors' tree map is well sorted.
We can see some white lines, but they are not scattered. It looks like the problem is due to incorrect rounding numbers.

The bug occurs because the number of data is higher than the number of pixels.
The image painted on the main view contains white lines but they are overlapped with the red lines. In the "original" image, the white lines are not overlapped, hence the summary data (which is based on the original image) show the white dots.
