TOPIC:

the highlight color is incorrect: Page.java -> AddAnnotMarkup()
it takes RBG color, the blue value as red, and red as blue in highlight annotation.
how to repeat: run demo -> select text -> highlight, now the default yellow highlight will be changed to aqua.
other types of annotation haven't this problem (underline/strikethrough/squiggly etc.)

OK, fixed.
plz, wait next beta.
