Not enough accuracy with Context::is_pointer_over_area

[davidhozic]

Hello, I'm trying to use the Context::is_pointer_over_area method to determine if any of egui widgets are being covered. This information is then used to ignore events in winit.

The method works great most of the time, but it seems that it's not 100 % accurate. It turns out that the method returns falsewhen the pointer is technically outside a widget but the widget can still be resized.

Here's an example of my problem. If the mouse is moved just outside the window, I no longer detect the window as being covered, thus events are also being processed by my winit processing code. Is there a way to add extra tolerance, so that Context::is_pointer_over_area will return true when the pointer is slightly outside the window?
