[TxMt] Appearance of HTML Output "isBusy" indicator?

[Steve King]

Is there some way to control the appearance of the spinning progress 
indicator on the HTML output pages?  Some CSS, maybe?  I'm writing a 
command using the standard themes given by webpreview.rb, but the spinner 
is practically invisible.  I don't want to turn it off (I know about 
TextMate.isBusy) or make any drastic changes, just change the color.
