Document: Fix window cascade

Removing the pointer fixed the cascade, and now new document windows
open shifted by a full titlebar height.

Did a bit of searching on GitHub for `-cascadeTopLeftFromPoint:` and
found this code that does what I was trying to do:

https://github.com/dsa28s/android-studio-apple-m1/blob/c555e84728bfd82a0f9e705af012da37fb52291f/src/java.desktop/macosx/native/libawt_lwawt/awt/AWTWindow.m#L1399

The above code taught me about the `NSEqualPoints` function, which is
basically what I wanted to initialise the variable. But now I suppose I
don't actually need to do an initialisation of the variable.
