Description Tobias Liefke

The SWT version of GC defines two methods for computing the "extent" of a string:
1. textExtent(String string)
2. textExtent(String string, int flags)
RAP only offers the first one. As text measurement in RAP is not as accurate anyway, I would suggest to implement the second method, too, just for single sourcing. We can ignore the flags for now and just return the same result as the first method (maybe add a "TODO" for inspecting the flags later).

I agree that we can implement this method.

The text size measurement *is* accurate in RAP. The exact sizes are measured on the client and reported back to the server.

I don't think that we have to ignore the flags. We should be able to support them by applying the requested changes to the text (such as replacement of mnemonics) before measuring.
