A basic class like Length should not depend on something from
frontend.
This change allows to remove several dummy implementations of
theFontMetrics().
This helper method is used to set the inset dimension cache at metrics
time. However this is already done by the metrics code itself
(MathRow::metrics, TextMetrics::redoParagraph), so that there is no
need to do this same work again in a different place.
Also, InsetPhantom::metrics is removed, since it does not do anything
interesting.
This commit comes with a mild risk attached (it might be that some of
these calls were useful after all!), but all of this is fixable.
Up to now Inset::dimension was either a helper function to access
CoordCache, or... something else. This created problems to properly
use it.
In particular, the definition of InsetText::dimension created problems
for child classes. Removing this definition (actually renaming it to
dimensionHelper) allows to streamline the code.
These were all found by cppcheck. Even in constructors that are there "only
because of std containers" the class should be initialized correctly. You can
never know whether such an object does not get used, and then a nice crash
caused by dereferencing a NULL-pointer is better than undefined behaviour.
There is no need for real-valued line width in painters. Actually, this even leads to uneven dashes for continuous spell checker.
The new code is supposed to be equivalent to the old one, just more readable. From this, we can try to see whether some lines need to be made thicker on HiDPI screens.
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29
In digital typography, the best value to use is the point size of the font.
* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
Convert code to use it.
* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.
* Fix several places where Length::inPixel is used without a proper em value.
* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.
* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.
so we can write a limited amount when using this for TOC and
tooltip output.
This should solve the problem with slowness that Kornel noticed,
which was caused by our trying to write an entire plaintext
bibliography every time we updated the TOC. We did that because
he had a bibliography inside a branch, and we use plaintext for
creating the tooltip that goes with the branch list.
Other related bugs were fixed along the way. E.g., it turns out
that, if someone had an InsetInclude inside a branch, then we would
have been writing a *plaintext file* for that inset every time we
updated the TOC. I wonder if some of the other reports of slowness
we have received might be due to this kind of issue?
counting when exporting to latex. This is done for the code comprised
between \begin{document} and \end{document}, while the preamble code
still needs manual calls to TexRow::newline() for registering new lines.

blank lines may be inadvertently output. This is achieved by using two
special iomanip-like variables (breakln and safebreakln) in the lyx::
namespace. When they are inserted in the stream, a newline is output
only if not already at the beginning of a line. The difference between
breakln and safebreakln is that, if needed, the former outputs '\n'
and the latter "%\n".
In future, the new class will also be used for counting the number of
newlines issued. Even if the infractrure for doing that is already in
place, the counting is essentially still done the old way.
There are still places in the code where the functionality of the
class could be used, most probably. ATM, it is used for InsetTabular,
InsetListings, InsetFloat, and InsetText.
The Comment and GreyedOut insets required a special treatment and a
new InsetLayout parameter (Display) has been introduced. The default
for Display is "true", meaning that the corresponding latex
environment is of "display" type, i.e., it stands on its own, whereas
"false" means that the contents appear inline with the text. The
latter is the case for both Comment and GreyedOut insets.
Mostly, the only visible effects on latex exports should be the
disappearing of some redundant % chars and the appearing/disappearing
of null {} latex groups after a comment or lyxgreyedout environments
(they are related to the presence or absence of a space immediately
after those environments), as well as the fact that math environments
are now started on their own lines.
As a last thing, only the latex code between \begin{document} and
\end{document} goes through the new class, the preamble being directly
output through odocstream, as usual.

menus were (intentionally) missing, and it turns out they were needed.
Normally all invocations of INSET_MODIFY should trigger a recordUndo now.
Of course all cases have not been tested, but it should be working.

- honor Abdel as author
- reintroduce the /// spacers in the header file because it makes it better readable and we do this in all other inset header files

We are now getting much closer to LateX drawing...

- this line is defined with a width of 1pt -> therefore also draw it in this size in lyx
- this line is by default black -> use black
- setting a color for this in the preferences is wrong and senseless, because the color of this line is defined by the color chosen in the text style dialog -> remove preference color
