In the VISG editor (see url) the tooltips aren't resized and painted properly.
Works on windows.

Developer explanation (copied below without screenshots):

As you may see, the button tooltip has the same size as in winxp.
This is correct, but it is not painted. I think, it's because ROS paints the
tooltips not via WM_PAINT.

And the second: the window tooltip with little screenshot...
It is not painted and has wrong size.
I think, it's because this tooltip didn't have LPSTR_TEXTCALLBACK as its
caption (in other words, it has direct caption). I resize the tooltip on
TTN_SHOW message. But, as I see, there is no such message for the window
tooltip. But the winapi documentation says TTN_SHOW is sent when the tooltip is
about to be shown. And no matter, has it LPSTR_TEXTCALLBACK or not. The button
tooltip has LPSTR_TEXTCALLBACK instead of its caption, and it's resized
correctly.

So, I think, there are two bugs:
1) painting tooltips not via WM_PAINT.
2) not sending TTN_SHOW, if the tooltip did not have LPSTR_TEXTCALLBACK.
