Basic text rendering working;
Added Font (done) and SymbolFont (skeleton); Added styling to set; Added CountourMap; Some script fixes git-svn-id: svn://svn.code.sf.net/p/magicseteditor/code/trunk@73 0fc631ac-6414-0410-93d0-97cfa31319b6

* - index An index in the input string.

* For cursor positions char_id = 0 means the cursor is BEFORE character 0
|
||||
* - pos The position of a character in real world x,y coordinates (in pixels)
|
||||
* The position is the top-left of the character.
|
||||
* A char_pos is often only the x coordinate.
|
||||
* A line_pos is often only the y coordinate.
|
||||
* - Line A line on the screen, this does not neccessarly correspond to explicit linebreaks,
|
||||
* since textwrapping also leads to a new line.
|
||||
* - line_id The index of a line, 0 is the first line.
