Use GTK_UNIT_INCH when printing to provide consistency across OS Tests have shown that the most multi-platform way to do printing with GTK is to use GTK_UNIT_INCH (or GTK_UNIT_MM) with GtkPrintOperation. Tested on Linux, OSX, Windows. However this requires the appropriate scaling for Pango and Cairo to be done, with separate plotting logic for printing and drawing on the screen. To achieve that, profile.c:plot() now accepts a scaling parameter from type "scale_mode_t" defined in "display.h". Also due to new scale, small decimal numbers (such as 6.12345) cannot be well stored in "cairo_rectangle_int_t" therefore it is replaced with "cairo_rectangle_t", which uses doubles to provide Cairo with a drawing area.

Add the capability to print a dive profile Ok, this is the ugliest f*&$ing printout I have ever seen in my life, but think of it as a "the concept of printing works" commit, and you'll be able to hold your lunch down and not gouge out your eyeballs with a spoon. Maybe. I'm just doing the cairo display as-is for the printout, which is a seriously bad idea. I need to not try to do colors etc, and instead of having white lines on a black background I just need to make thelines be black on white paper. But that would involve actually changing the current "plot()" routine, which is against the point of the exercise right now. This really is just a demonstration of how to add printing capabilities.

Calculate dive maxima/minima independent of dive computer This splits the dive time, depth, pressure and temperature maxima and minima setup from the per-dive-computer "create_plot_info()" function into one setup function that walks _all_ the dive computers, so that we have a global maxima and minima. That way the graph scaling we set up will now fit the data from all dive computers rather than just the particular one we are plotting. So if you switch back-and-forth between computers, the scale (which is defined by the extremes) remains the same.

If you mouse over an event, that is still shown in the tooltip, but even in the absense of events, the tooltip will be active, and mousing over the profile area will show the time, depth and pressure.

Show the actice divecomputer's data in the Info notebook While the profile switched between different divecomputers, the Dive Info notebook always showed either information from the first divecomputer or (with some of the recent changes) information that had been collected from all divecomputers and somehow consolidated for the dive. With this commit we now show the data from the same divecomputer that is also shown in the profile (which means if some data is available from one of the divecomputers and not from another that will be correctly reflected in the Dive Info notebook as the user cycles through the divecomputers. This does beg the question if we should have some kind of "best data available, considering all divecomputers" mode - but that's definitely not something I'll tackle prior to 3.0.

If unselected (default) we get the actual disposition. If selected, switches blocks. 3.- Add two buttons with labels to set the height of the profile, and tanks. We select the percentage of layout occupied by each option, reserving 7% for the header (non adjustable), and assign the rest to notes. - Values in % have got hardcoded min/max (e.g. being the profile a major feature of subsurface, would be meaningless make it < 37%) - The values are initialised to the actual ones, so leaving them untouched defaults to the old printout.

Add a "View next dive computer" menu item This adds the capability to actually view all your dive computers, by adding a menu item under "Log"->"View"->"Next DC" to show the next dive computer. Realistically, if you actually commonly use this, you'd use the accelerator shortcut. Which right now is Ctrl-C ("C for Computer"), which is probably a horrible choice. I really would want to have nice "next/prev dive" accelerators too, because the cursor keys don't work very well with the gtk focus issues. Being able to switch between dives would also make the "just the dive profile, maam" view (ctrl-2) much more useful. The prev/next dive in the profile view should probably be done with a keyboard action callback, which also avoids some of the limitations of accelerators (ie you can make any key do the action). Some gtk person, please? Anyway, this commit only does the dive computer choice thing, and only using the accelerators.

Separate Gtk related code from core logic: info Surprisingly straight forward, just a couple of places where we really mix significant logic with UI code (for example setting the window title). I had to move amount_selected from display-gtk.h to display.h - I guess the number of dives that are selected is UI independent. But I wonder if we still will track this as a global variable in a Qt UI (since the Gtk selection logic is the main reason this existed in the first place).
