Timeline: consider how to manage size and layout of timeline contents

Browse source 
bottom line is to do most autmatically, and to establish a slave-relation
navigation-area -> timeline-ruler
header-pane-content -> corresponding track-body

this can be accomplished mostly by connecting the aproprieate signals,
thus these widgets will live within the Layout-Manager, which consequently
is renamed into TimelineLayout

The primary author(s) and the year of the initial copyright claim should be mentioned.
- Each header should be focused on a specific purpose. Preferably it starts with a file-level
doxygen comment explaining the intention and anything not obvious from reading the code.
At lest a `@file` tag with one line of classification in a doxygen comment at the top of every
file is mandatory.footnote:[this rule stands simply because, without such a file-level doxygen
comment, doxygen will _ignore all contents_ of this file (really, might be surprising, yet it is
the way it is...)]
- when arranging headers and compilation units, please take care of the compilation times and the
code size. Avoid unnecessary includes. Use forward declarations where applicable.
Yet still, _all immediately required direct dependencies should be mentioned_, even if already

- The include block starts with our own dependencies, followed by a second block with the library
dependencies. After that, optionally some symbols may be brought into scope (through +using+ clauses).
Avoid cluttering top-level namespaces. Never import full namespaces (no +using namespace boost;+ please!)
Avoid cluttering top-level namespaces. Never import full namespaces.footnote:[no `using namespace gtk;`
or `using namespace boost` please! Experience shows, in the end you'll be using 5 names or so, but
pull in all the others just for sake of laziness. Just type the f**g `using` clause for every
import individually, and we'll all be better off...]
- the includes for our own dependencies shall be given relative to source-root (or test root). Don't use
relative includes for headers located in the same directory, or -- worse still -- in the parent directory.
- sometimes, the actual translation units will combine several facilities for technical reasons, e.g.
when sharing an implementation-level class or even singleton instance.
- sometimes, the actual translation units will combine several facilities for technical reasons.footnote:
[this means, there can be ``headers'', which are actually only be intended for inclusion on one or two
distinct places. This should be mentioned in the file-level comment, but generally is an acceptable
practice, and better then lumping everything into a 1000 lines header. As a guideline, if you expect
a rather technical concern not to be of much interest for most readers of a header, then better
extract it into a separate self-contained header and include it. E.g., you might be sharing an
an implementation-level class or even singleton instance and some constant definitions. Just
be sure not to include definitions several times.]
Anonymous namespaces should be used liberally to avoid unnecessary exports.
- template code mostly needs to reside in headers. (same for metaprogramming code).
We employ the simple inclusion model (``Borland model'') for template instantiation.
