Avoid GDI DC exhaustion from calling DPI

[eugenesvk]

I'd like to show a tooltip-like window near a mouse pointer, for I poll for its position and on each call check dpi (in case the mouse moves to a different monitor) to update the size of the tooltip accordingly if dpi changes

However, I've noticed that this generates a lot of GDI DC handles

Is it simply missing an extra releasedc call after calculating DPI?
