Ok, so after messing around with the Aura skin.xml file, I managed to trim off the sides and the bottom by changing the <EXTERNALAPPS> settings to this:
<EXTERNALAPPS>
<X>0</X>
<Y>100</Y>
<WIDTH>848</WIDTH>
<HEIGHT>310</HEIGHT>
<FULLX>0</FULLX>
<FULLY>0</FULLY>
<FULLWIDTH>846</FULLWIDTH>
<FULLHEIGHT>490</FULLHEIGHT>
<APPX>-15</APPX>
<APPY>49</APPY>
<APPWIDTH>878</APPWIDTH>
<APPHEIGHT>290</APPHEIGHT>
<FULLAPPX>0</FULLAPPX>
<FULLAPPY>50</FULLAPPY>
<FULLAPPWIDTH>848</FULLAPPWIDTH>
<FULLAPPHEIGHT>428</FULLAPPHEIGHT>
Now I cant figure out how to trim off the top. The top menu bar is there no matter what I try changing the values to.
