the majority has bigger screens, this can be turned on by default again.
Thanks pancake, for the hint.

invert mode now works as expected. In the config.def.h autohint is set to
false, so the fonts are drawn correctly, without any overlapping.

patch to fix the font symbols in all fonts should make it easier to choose a
better font.

activating antialiasing.

TERM set back to xterm.
changed default fonts.
Note: drawing is now (even) slower.

use config.def.h mechanism
add SHELL in config.h

along with duration in config.h, factored some code in tnew()/treset()
and cleaned some code.

results in a lot of simplification :
	- no more dirty flags (perf are good enough).
	- no more ugly gfx call in emulation functions.
LINESPACE removed from config.h.
BORDER is now handled correctly.

visibility of the cursor is not saved/loaded anymore.
scrolling up/down is fixed.
added RI and RIS sequences.
fixed cursor drawing bug.

cursor keys are handled in kpress according to the Application Mode (DECPAM).
define & enum were renamed.
tcursor() is now tmovecursor() which is more correct.
tcpos() is now tcursor(), as DECSC is also supposed to save attributes.
capnames are indicated whenever possible.

Currently:
alsamixer looks fine, totally usable.
ncmpc is almost ok.
emacs looks like shit.
