public class MaWiRic
extends SvgSource

Translation of tscore source according to "Mathias Wittekopf/Vorübergehende Zustände/8. Satz/meditation 2(ricercata)"; see ohrwelt.de.
Generates a dynamic SVG with a matrix of text characters in an equidistant font, which are made visible and invisible again, all individually, controlled by the score.
The main example score is sig/examples/tscore/mawiric1.tscore.

The score has two synchronuous voices, one for switch-on events and a second for switch-off events. Both voices have only their main parameter (see Event.main_parameter_name). Switch-on events are given by line and column and apply to this coordinate.
Switch-off events are given by character content and apply to all these characters.
In the form used in the prototype, there is a first phase of switch-on, and a second of switch-off, both slightly accelerating. Only the former contains synchronuous events.
Despite being very simple, there is a whole bunch of consistency constraints:

1. Switch-on events must have valid coordinates (line and column number)
2. Switch-on events must only hit non-blank characters.
3. No duplication of switch-on events, ie. all switched on positions must currently be switched off.
4. No duplication of switch-off events, ie. at least one position with such a character must currently be switched on.
5. Switch-off events should refer to characters which occur in the text.
6. Switch-off events should refer only to non-blank characters.
7. All non-blank positions should be switched on once.
8. All characters should be switched off at the end.
9. ( There should be one moment where all characters are visible. )

Violations are currently reported as WARNINGS, not as errors!
This code can be used differently than MW's original, since the strict separation into two phases (on and off) is NOT ensured by the code.

Code generation scheme for each character position = coordinate, "Z" is the character text:

    [text opacity='0.0' x='..' y='..7']Z
      [set attributeType='XML' attributeName='opacity'  to='1.0' begin='SWITCH-ON-TIME'/]
      [set attributeType='XML' attributeName='opacity'  to='0.0' begin='SWITCH-OFF-TIME'/]
    [/text]
  

Further variants are possible, but not implemented:

1. multiple switch-off of the same character can be applied to subsets of the visible characters.
2. switch on and switch off treated symmetrically: Both can be given by position and/or by character content.

Technically this is a sub-class of SvgSource. The methods update() and convertData() are called and must be defined.
