The library takes care 36of programming the actual video hardware, and provides a number of simple 37functions to do various graphic operations. 38 39There is also support for a mouse via the standard mouse system in FreeBSD, 40including the ability to transparently have a mouse pointer superimposed on 41the graphic image currently being worked on. 42 43The library takes care of screen switching by storing the current image in 44memory before switching to another virtual console, and restoring when the 45user switches back. This allows several graphic applications at once, but 46on different virtual consoles. 47EOD 48 49annotations { 50 set = "optional,optional-jail" 51} 52
