Caca limitations and bugs

The caca terminal has known bugs and limitations:

Closing the terminal window by clicking the "X" on the title line does not work correctly. Press "q" to close the window.

Unicode support depends on the driver and the terminal. Bright background colors may cause blinking. Modifier keys are not supported for mousing, see term caca (p. [*]).

Rotated enhanced text, and transparency are not supported. The size option is not considered for on-screen display.

In order to correctly draw the key box, use

     set key width 1 height 1

Alignment of enhanced text is wrong if it contains utf8 characters. gnuplot dies when running from a script when using the "ncurses" driver. Illegal utf8 sequences might lead to an endless loop in libcaca (now fixed upstream). Resizing of x11 windows does not work on some systems. Changing the input focus to the text input window when pressing 4#4space5#5 does not work reliably in wgnuplot.
