Title bar always present in GRProWindow

[Urethramancer]

GRProWindow with title bar unticked still shows the title bar and close/max/min controls. The workaround I use to get roughly the same effect is simply to make the default NSView a GRProBox, and it looks alright.

Borderless window mask is not currently supported, if you want to have a borderless window now just use a standard NSWindow and set the background color to kProWindowBackgroundColor

Alright, cheers!

I am reopening this because the solution I proposed is just a workaround, I will actually fix the issue soon :)

Oops, didn't mean to close it! On minimal sleep here :P
