No visible way to close the preferences dialog on Mac OS X

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open Stencil
2. Open the preference pane by clicking on Evolus Pencil -> Options...
3. Try to close the preference pane

What is the expected output? What do you see instead?
I expect to see a visible button to dismiss the pane. All I see is a pane and 
no visual guide to dismissing it (see attached screenshot). The only was to 
dismiss the pane is by using the keyboard (either press Esc or Cmd+W)

What version of the product are you using? On what operating system?
version 2.0.3 on Mac OS X Mountain Lion

Please provide any additional information below.
The about screen which is quite similar offers a "Close" button (see attached 
screenshot).

Seems you have to press the Esc button to close the Options dialog!! 

However this is non-standard Mac functionality though. Should have OK and 
Cancel buttons at the bottom or at minimum the close/minimise/maximise buttons 
top left
