[BioC] browseGenome width question (rtracklayer)

[Mark Robinson]

Hi all.

Been using 'browseGenome' to send some data tracks (wig files) to the  
UCSC genome browser.  This all works beautifully.  For example:

 >        browseGenome(trackSets(track),segment=genomeSegment(track))
A genome browser session of class 'ucscSession' with 1 views and 183  
tracks

I'm wondering if there is a way to set a width parameter for the image  
that gets displayed within the browser (i.e. the GIF file that UCSC  
creates with all the track).  By default, every new window opens with  
an image of width 620 pixels.  I'd like to make that something like  
1000 pixels if possible.

Cheers,
Mark
