Message:
  • src/graphics: + Initialise the char buffers in the X11 driver.
  • src/io.c: + caca_get_event() and caca_wait_event() immediately return zero if

event_mask is zero.

+ Added support for the Home, End, PgUp? and PgDown? keys.
+ In the S-Lang driver, added a call to SLang_getkey() before the call to

SLkp_getkey(), otherwise a single Escape call will not be interpreted.

  • test/event.c: + The "quit" sequence now quits the program, instead of "q" alone. + Added a status bar below.
