change/update events the first time a line is drawn

Hi Marjin,

I coming to this again with a more clear request that I think will be very useful in general.

Is it possible for you to implement an event similar to ‘beforeChange’ that fires before a line is rendered (that is renderLine is called) for the first time. (‘beforeFirstRender’ ?)

It is very useful to be able to do stuff before a line is drawn for the first time. For example it will allow indentwrap to be implemented much more cleanely without the renderLine hack.

Thank you!
Micha
