In the Windows version, there is a resolution drop down menu at the left 
side of the tool bar. It propose a set of default dimensions and 
anti-aliasing settings.
You can easily expand it, it's an ini file,a simple text file following 
a simple set of rules.

You can also enter any arbitrary dimension in the text box just next to 
the drop menu.
Use +wnnn to set the width.
+hnnn to set the heigth
+a is used to turn on anti-aliasing followed with some options to fine 
tune it
Ex.: +a0.01 +am2 +r3
Turn anti-aliasing on with a trigger delta of 1% in the sum of the 
difference in the value of neighbour pixels, using anti-aliasing method 
2 and a recursion level of 3.
