Christoph Lohmann 2752018e27 This adds the fontcache dependency to try something out. Additionally the
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.

Christoph Lohmann 0d88f1ef75 Thanks to c00kiemon5ter. Not changing bold to bright colors seems to be the
right choice.

Christoph Lohmann ed5b8700a6 We need all the colors to be available, so die() on some not available.
This is a new opportunity to see if X11 somewhen handled colors in a strange
way.

Roberto E. Vargas Caballero 3af49e34f6 Allow control characters inside escape sequences
Taken from vt100 manual programmer:

	Control characters (codes \0 to \37 inclusive) are specifically
	excluded from the control sequence syntax, but may be embedded
	within a control sequence. Embedded control characters are executed
	as soon as they are encountered by the VT100. The processing of the
	control sequence then continues with the next character received.

Roberto E. Vargas Caballero a7d7e29300 Ignore all control characters not handled
Taken from vt100 programmer manual:

	Control characters have values of \000 - \037, and \177. The control
	characters recognized by the VT100 are shown in Table 3-10. All
	other control codes cause no action to be taken.

We have to take attention when we are using alternate charset, because in
this cases they are not used as control characters.

Roberto E. Vargas Caballero eb360e5fd1 Fix bug in tputc writing to io file
If -f options is enabled then tputc() writes all the data to a file. Actual
code assumes that all the strings in 'c' parameters have always 1 byte
length, but this is not always true, because due to utf-8 encoding some
characters can have a diferent length. So it is necessary pass string length
to tputc in order it can call to write() correctly.

Roberto E. Vargas Caballero b6cfff1625 Clear X window in tsetreset()
tsetreset() is called when it is necessary a full initialization of the
terminal, so it also should clean the full X window and not only the
terminal content. It is necessary change the order of the
initialization in main(), and put xinit before of tnew(), because tnew()
calls to tsetreset(), and  this can cause a call to xreset() with
incorrect values.

Roberto E. Vargas Caballero 4876d6e05b Clean windows display after resizing
Some times the size after a resizing is not an exact multiply of a number of
characters, so redrawn the screen using the lines and columns of the neww
size can cause that some old graphics keep in the screen. Solution is clean
all the windows with the background color.

Roberto E. Vargas Caballero 88a8f85a8a Copy non set positions as spaces
st selection don't insert in the selection position whose value is not
set. This is correct for the positions in the end of the line, but cause
some problems in the beginning. For example echo -e 'a\tb' will print in the
screen:

a	b

but after selecting and copying in some place you get:

ab

because positions from 1 to 7 don't have any value. This patch deals all
positions without value as blank (even at the end of the line).

Roberto E. Vargas Caballero d81250e5f9 Fix selection bug
After the commit named "Remove timeout in the main loop", selection is not
working in the proper way. After selecting something, press mouse button in
a line outside of selection causes an incorrect highlight. This patch fix
the problem forcing a draw after the press event, but this is only a fast
hack. Real solution means rewriting selection code.

Roberto E. Vargas Caballero c5a9b799d4 Render only once in each main loop iteration
draw() runs over all lines of the screen and renders only the dirty lines,
this avoids render lines which are not modified since last draw() call. In
this moment the main loop is something like:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Call draw() for rending
     - Read X events

This cause the problem that all the X events that have to update the screen
have to call draw() (because draw() is called before of X events handling),
so you can have multiples renderings in only one iteration, that will waste
a lot of resources.

This patch change the main loop to:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Read X events
     - Call draw() for rending

So X events don't have to worry about rendering, because draw() is called
after them.

The only place where draw is called outside of the main loop is in redraw(),
but it is necessary for getting a good tput flash.

Roberto E. Vargas Caballero 85849ce72a Remove timeout in the main loop
The main loop waits until there is some data to read in file descriptors of
the X server or the pseudo tty. But it uses a timeout in select(), which
causes that st awake each 20 ms, even it doesn't have something to do. This
patch removes this problem removing the timeout, which is not needed.

Roberto E. Vargas Caballero ba1e9daeef Call XdbeQueryExtension before of calling any Xdbe function
XdbeQueryExtension() tells to the caller if the Xdbe extension is present in
the X server, so it should be called for sanity. But like is said in
XdbeQueryExtension(3):

	No other Xdbe functions may be called before this function.  If a
	client violates this rule, the effects of all subsequent Xdbe calls
	that it makes are undefined.

it is mandatory call this function.
