* Optional support for subtitles
*
* CHECK what happens in VQA where the audio plays separately (are the finales such VQAs ?)
* TODO? Use another escape sequence to progressively display text in a line (like in SCUMM games) <-- this could be very useful with very long lines
* - might also need an extra manual time or ticks parameter to determine when during the display of the first segment we should switch to the second.
* TODO? A more advanced subtitles system:
* TODO: subtitles could be independent from sound playing (but probably should disappear when switching between UI screens)
* TODO?: Support for queuing subtitles when more than one subtitle should play for a spoken dialogue (due to a very long quote)
* TODO?: Predefine a minimum time for a subtitle to appear, before it is interrupted by the next one. (might need queuing)
* TODO?: If the subtitle is the last one then extend its duration to another predefined delay.
*
* DONE Removed support for internal font TAHOMA18 - this particular font is corrupted!
* DONE Create and Support proper external FON for subtitles.
* DONE split at new line character (priority over auto-split)
* DONE auto-split a long line into two
* DONE support the basic 2 line subtitles
* DONE support a third line for subtitles (some quotes are too long for 2 lines). Are there quotes that are too long for 3 lines?
* DONE handle missing subtitle files! Gracefully don't show subtitles for VQAs or in-game dialogue if the required respective files are missing!
* DONE add subtitle files for the rest of VQAs that have spoken dialogue
* DONE A system to auto-split a dialogue after some max total width of character glyphs per line.
* DONE - OK - CHECK What happens with skipped dialogue (enter / skip dialogue key pressed)
* DONE - OK - CHECK what happens in VQA when no corresponding TRE subs file?
