sample program for reproducing FillRect bug

I have a program that uses CPaintDC.FillRect() to draw histogram samples.

It draws one-pixel wide vertical rectangles.

Under wine, the bottom-most pixel is not drawn.

I'm attaching a sample program.  Under Windows7 (have 64bit pro), the red line
is touching the black baseline and the black line on the right is touching the
baseline also.

When I run the program under wine, both the red vertical line on the left and
the black vertical line on the right are floating one pixel above the baseline.

I tried both 32bit Ubuntu 11.04 (wine 1.2.2) on a netbook and also Fedora 15
64bit (wine 1.3.21) under Virtualbox on my Windows machine.  Both have the same
problem.

The relevant code for the test case is in

CChildView::OnPaint() in ChildView.cpp
