* Text properties have a type, which can be used to specify highlighting.

* TODO:
* - mismatch in column 1 being the first column
* - Let props overrule syntax HL.
* - When deleting a line where a prop ended, adjust flag of previous line.
* - When deleting a line where a prop started, adjust flag of next line.
* - When inserting a line add props that continue from previous line.
* - Adjust property column and length when text is inserted/deleted
* - Add an arrray for global_proptypes, to quickly lookup a proptype by ID
* - Add an arrray for b_proptypes, to quickly lookup a proptype by ID
* - Perhaps we only need TP_FLAG_CONT_NEXT ?

* - Add an arrray for b_proptypes, to quickly lookup a prop type by ID
* - Checking the text length to detect text properties is slow. Use a flag in
* the index, like DB_MARKED?
* - Also test line2byte() with many lines, so that ml_updatechunk() is taken
* into account.
* - add mechanism to keep track of changed lines.
