PATCH: Compose Coordinates *FINAL*

[Ali Akcaagac <ali akcaagac stud fh-wilhelmshaven de>]

hello,

first of all, sorry for bombarding the mailinglist with my
compose window coordinates stuff but sometimes you are going
with some ideas... well ok.

now i am finished so far, everything works as it should and i
really would like to get some of you guys testing this.

please apply this patch to a recent balsa CVS, this version
works 100%, no crashes, no wrong coordinates or whatever.

here a feature list so far:

- output of textsize in bytes. if you type more text, the size
  gets increased dynamically. in the statusbar you get this with
  e.g. 'Size: 2345 bytes'

- outputs the amount of lines in your text. value gets changed
  whenever you add or delete lines. statusbar show you this
  e.g. 'Lines: 12'

- output of amount of words written in your text. only separated
  by spaces, tabs or newlines. same stuff as written in ansi-c
  by kerninghan & ritchie :) you get this in the statusbar
  e.g. 'Words: 2012'

- output of index to the statusbar, showing you the real position
  within the text itself.
  e.g. 'Index: 1232'

- output of the coordinates. this one is selfexplainatory
  X: 4, Y: 2

- output of the char infront of the cursor, you get the output
  in hexadecimal value and the ascii value itself. sometimes
  you work and see a certain char and want to know what value
  it is, so you can reproduce it quickly. the best is you get
  also the output of the < 0x20 chars, e.g. null, linefeed,
  carriage return and whatever. specially fine if you include
  windows related textfiles or you include textfiles with
  special ansi sequences.

well, i worked really long on this patch, its nothing special
but figuring out GTK was a mess, since not everything was
explained everywhere, i needed to tweak in the gtk code itself.

so far. i would really like to get a reply. test it and reply,
if you detect some unbehaves.
