[Gmod-ajax] alignment2 callback to color reads based on length

[Ke J. <bio...@gm...>]

Hi,

I'm trying to write a callback function to color the bam alignment2 reads
based on the read length. I went through the BAM/LazyFeature.js, looks like
the length_on_ref parameter is what I'll be after as there was no gaps
allowed in our mapping. But I'm having trouble writing the callback as I'm
too fresh with javascript. Is there an example of such callback functions
working with bam/alignment2? Or maybe anyone could point me to the code
that define the current color scheme so I could take a look?

Thanks!

Ke
