Change `Window::physical_cursor_position` to use the physical size of the window #9657

…tion is inside the window but it constructs the bounding rect for the window using its logical size and then checks to see if the cursor's physical position in inside the rect. When the physical size is smaller than the logical size, this leaves a dead zone where the cursor is over the window but its position is unreported. This commit changes the rect so it's the physical size.
