Forcing web pages to anti-aliase
Here is an observation that has started to riddle me and perhaps someone can enlighten me. When a web page (or desktop page for that matter) uses the standard font, it is not anti-aliased, unless the user opts in to do so via the desktop settings.
It appears however that fonts are not automatically anti-aliased on some web pages, even when anti-aliasing is switched on, why? Moreover, when changing the font to something other than black (#000), say darkgrey (#333), anti-aliasing is effected, why?

Note: there is a marginal performance decrease when anti-aliasing is switched on, which on modern day computers is so immeasurably small, that the opt-in is actually riddling me more, because it might as well be switched on by default, but perhaps that is distribution dependent.

robot-playernav

robot-playernav(1)					      General Commands Manual						robot-playernav(1)

NAME

       robot-playernav - GUI client to control over localize and planner devices

SYNOPSIS

       robot-playernav [options] <host:port> [<host:port>...]

DESCRIPTION

       robot-playernav	is  a  GUI  client that provides control over localize and planner devices. It allows you to set your robots' localization
       hypotheses by dragging and dropping them in the map. You can set global goals the same way, and see  the  planned  paths  and  the  robots'
       progress toward the goals. robot-playernav can also display (a subset of) the localization system's current particle set, which may help in
       debugging localization. You can think of playernav as an Operator Control Unit (OCU). robot-playernav can also be used just to view a map.

OPTIONS

       -fps dumprate
	      dump screenshots rate in Hz (default: 5Hz).

       -zoom zoomlevel
	      initial level of zoom in the display (default: 1).

       -aa {0|1}
	      use anti-aliased canvas for display (0 == false; 1 == true).  The anti-aliased canvas looks nicer but  may  require  more  processor
	      cycles (default: 1).

       -map map_idx
	      the index of the map to be requested and displayed (default: 0).

AUTHOR

       Debian Project.
