Subject: :Page): Added thumb object parsing. (Page::display) (Page::displaySlice):

2004-01-13  Remi Cohen-Scali  <rcoscali@cvs.gnome.org>

	* xpdf/Page.cc (Page::Page): Added thumb object
	parsing.
	(Page::display) (Page::displaySlice): Add CB for
	annotations in Page display.
	(displaySlice):
	Added conditional display of annotation in order to
	avoid them when USE_ANNOTS_VIEW is not defined.
