Improvements to cursor highlighting in the source panel
* TexRow now computes rows from a DocIterator. In practice, the cursor highlighting is now correct inside insets, it is no longer restricted to the topmost level. It certainly also makes forward-search more precise. * Added the option to disable a texrow when not needed, for perf. * Fixed a bug where the last paragraph was not properly highlighted. Limitations: * TexRow still does not handle: math (e.g. multi-cell), sub-captions, inset arguments.
