Fix treeview with checkboxes creation

[Maxime Bellengé]

Sorry, I sent the last mail a bit quickly.

The rest of the patch is important in my opinion because without it, the
drawing is done black and white. So you can reduce the patch to that
only line but it is not what I wanted. 

-       hdc = CreateCompatibleDC(0);
-       hbm = CreateCompatibleBitmap(hdc, 48, 16);

hbm is a 1 bit per pixel bitmap

+       hdcScreen = CreateDCA("DISPLAY", NULL, NULL, NULL);
+
+       hdc = CreateCompatibleDC(hdcScreen);
+       hbm = CreateCompatibleBitmap(hdcScreen, 48, 16);

hbm has now a screen compliant depth

In a treeview, the checkbox is not B/W. If there is another way to do it
please tell me. But I think this part of the patch is important
