Those if() blocks don't have any reason being there, as x and y are not
pointers. If the window is destroyed, just set the out values to zero
and return.

gdk_unicode_to_keyval(uc) returning (uc | 0x01000000) is not an
error return value but simply the way to encode 24-bit unicode
characters directly as keyvals.
When we use the style context to get information for the tab region,
also add a style class to indicate its position, so that the relevant
information is pulled off from the theme.

This is useful to e.g. theme notebook tabs differently according to
their position directly from the CSS sheet.
GtkNotebook support in a separate commit.

The setter for this was deprecated in 2.x and removed in 3.0.
I don't see any reason why we should hardcode 2px for this value;
instead, deprecated the getter and make it always return zero, and stop
using the variables internally.

The code before was basically adding and removing the same padding value
in two different places during the allocation cycle.
Instead, what we want to do is to offset the inactive tab allocation by
the difference with the active tab padding, to ensure the tab content is
always drawn centered and in the right position.

We want to enable the use of different padding values between active and
inactive tabs, so that the two are completely separated (but limited by
the active tab size).
This way themes can decide how bigger the active tab is drawn compared
to the normal one just specifying a different padding value from the
CSS, like this:
.notebook tab {
padding: 2;
}
.notebook tab:active {
padding: 4;
}
As a first step, fetch the padding values with the right state flags
from GtkStyleContext.
