Split string into words
This function takes a string and splits it into words. There are different mechanisms which indicate possible splitting points in the resulting word stream:
- self:SPACE: The renderer might render a space
- self:WRAP: The renderer might wrap the line at this position, but will
not render spaces, might as well just be omitted.
A possible splitting of an english sentence might look like:
1. array(
2. 'Hello',
3. self:SPACE,
4. 'world!',
5. );
Non breaking spaces should not be splitted into multiple words, so there will be no break applied.
