Snapping windows to the edge of the screen draws inconsistant snap pane

[AlexanderFaucher]

When you drag a window to the left or right edge of a screen an orange box is drawn to indicate you will snap the window if you let go. However, it appears if you don't move the mouse all the way to the edge the orange box doesn't actually represent where the window will snap. Instead it appears to linearly interpolate between the actual window size and the snap position based on distance from the edge of the screen. It seems like this should really be an animation when you enter/leave the snap region instead of fixed size depending on the mouse position. As is you the orange box doesn't represent what the window will snap too, just that it will snap.
