This is wrong because we don't really need to scale. We already
have the estimated page dimentions in pixels, so taking the
quotient of the printer DPI and screen DPI and then scaling
(probably up) our rendered widgets via the QPainter introduces
blur (due to the oversampling), and a performance penalty.
By rendering at the exact dimensions we ensure that the widgets
are crisp at a 100% printout.

With this option there is an exception, which makes the notes section of
the profile table occupy half the page. This way dive plans can reasonably
be printed.

I know everyone will hate it.
Go ahead. Complain. Call me names.
At least now things are consistent and reproducible.
If you want changes, have your complaint come with a patch to
scripts/whitespace.pl so that we can automate it.

QList is optimized for storing pointer-sized items, thus
a QVector is the better choice for everything else.

I can't really see any point in passing a local loop variable around,
and copying a uninitialized pointer. Better use local variables there
and let the compiler optimize them away if it feels for doing that.

estimateTotalDives() is used to calculate the total dives
to be printed, it requires a 'struct dive' pointer
and a couple of 'int' pointers for the iterator 'i' and
'total' return.

This patch adds a couple of classes and some other modifications
in PrintLayout that handle the printing of tables under a profile.
models.h : ProfilePrintModel
The class uses a 'struct *dive' to output all required data
for a certain dive at specific rows and columns. It also handles
font formatting and text alignment.
modeldelagatates.h : ProfilePrintDelegate
The class is used only for drawing a custom grid for profile tables.
PrintLayout::createProfileTable()
The function is used to create and setup the profile table object
PrintLayout::printProfileDives()
The function now has correct padding of dive profiles on a page
and also the printing of actual tables below them.

printlayout.cpp(h):
This patch cleans some test code and adds the function
printProfileDives() that accepts a number of dives
per rows and columns. It can technically fit any number
of dives on a page given the page size allows it. Both
landscape and portrait layouts are supported.
It now replaces the old methods:
printTwoDives()
printSixDives()
Space is reserved for data tables that will be placed
bellow profiles on a later stage.

The current QTextDocument implementation is slow due to
HTML parsing. By using QTableView with QAbstractTableModel
we boost the performance of the table print drastically.
This patch completely replaces the old solution.
There is a hidden QTableView widget which is populated
with all data and rendered using a QPainter attached to
the printer device.
A couple of new classes are added in models.h/cpp
that handle the table print model and these are then used
in printlayout.h/cpp.

(experimental)
Add the method PrintLayout::convertPixmapToGrayscale()
to convert a rendered profile pixmap to grayscale.
It will probably be faster to have
ProfileGraphicsView render in grayscale under certain
conditions (and use a specific color table) instead -
e.g.:
ProfileGraphicsView::setPrintMode(bool printMode,
bool useGrayScale);

It might be a good practice to declare certain class
'helper' functions as constant members. But I don't

than the readability ones.

- set individual column width and name

- reduce font size in the table

Currently only for the table print, but now we use the
actual dive table to iterate trough all dives (find only
selected if needed) and print their 'number' element
in table rows.
Also improves the new-page detection algorithm slightly.

PrintLayout for now only handles the table print,
while the data output itself is work in progress.
For now there is a simple HTML/CSS table logic based
on QTextDocument. There is an iterative algorithm
which listens for a page increase and adds a heading
on top of the new page.
