Known bugs with zapping, don't report them
------------------------------------------
* == Bug that needs fixing
! == Bug that needs fixing, very important
------------------------------------------

	* Need better no-overlay-present handling.
	! RPM creates incorrect zsfb.capps 
	* Capture won't work under PPC (endianess)
	* Look for endianness problems.
	* vbi eats too much CPU, investigate.
	~ Zapzilla: Calls fetch_page more often than necessary,
	  investigate.
	~ Zapzilla: what's v4lx doing on standard change?
	* check on_trigger_clicked
	* Overlay (no XVideo) under E is broken, shading the window
	  isn't correctly detected.
	* Do not assert on ESD timeout
	* Bug in save window geometry, reported by Pawel.
	* Auto-overlays search result pages.
	* zsfb.capps conflicts with RPM relocation.
	* config.h is also full of hardcoded paths.
	* Closing the main window while recording blocks.
	  Backtrace:
	  on_exit2_activate() [now quit_cmd()]
	  UpdateCoords()
	  zmisc_switch_mode(TVENG_NO_CAPTURE, main_info)
	    shuts down capturing before calling
	    plugin_close to stop recording, not good.
