We want to simplify our initialization code and remove all commandline
argument handling from it. The first stop for this is to reduce the
number of gtk_init variants we have.
i.e. when wrap-width > 0. This was only being done for non-grid cases.
So, ComboBoxes in grid mode did not indicate their selection when popped
up and required users to keynav from ‘nothing’ (at the top-left) to the
item they wanted to select. By selecting the active item in advance, now
it’s highlighted & acts as the starting point for keynav around the grid
This previously only mentioned its effect on the displayed value, and
even after the previous commit, its rounding of the actual value upon
change still reads like too much of an afterthought. Worse, it wasn’t
mentioned at all in the doc for the @digits parameter. Change this to
emphasise rounding always occurs and the displayed value is secondary.
Whether it should is an open question, but for now, the documentation
should clearly indicate that currently rounding is only applied upon
changes to the value, not to the existing value when ::digits changes.
This is already clear in the doc for the underlying Range::round-digits.
https://bugzilla.gnome.org/show_bug.cgi?id=358970
The documents state that gtk_scale_set_digits() “causes the value of the
adjustment to be rounded off to this number of digits, so the retrieved
value matches the value the user saw.” Note the lack of any condition.
But in fact, if draw-value was false, rounding was disabled on the base
Range, so values that weren’t displayed weren’t rounded. This made the
docs wrong and made an apparently cosmetic detail alter functionality.
Fix by ensuring the number of digits set on Scale is always propagated
along to gtk_range_set_round_digits(), thus rounding to it in all cases
when the value changes, regardless of whether the value is displayed.
This doesn’t address the other idea from Bugzilla: that changing the
number of digits should clamp the _existing_ value if it’s more precise.
This contradicts digits docs in the base Range, but the above from Scale
can be read as implying it’ll happen. For now, that’s an open question.

GtkFileChooserButton installs a handler for the popped-up signal, which
refilters the menu, in order to hide the “(None)” item from the popup
if it was previously selected in the ComboBox. This oddity means that:
• Until recently, this item would be selected in the menu shell, which
would then be popped up and change the selection away from that item.
This was therefore redundant (more on which below!) but benign.
• After the patch for https://bugzilla.gnome.org/show_bug.cgi?id=771242
however, this causes a critical assertion fail, as now we stash the
originally selected item in a pointer so that it can be selected only
after realisation/popup – but by that stage, the model has just been
refiltered and the previous pointer no longer refers to a valid item.
This commit works around this problem by, after popping up the menu,
getting the active item again, in case a popped-up handler has gone and
invalidated the pointer to the active item that we saved before popup.
If a handler does this, everything done to find/use the original item is
pointless. But this avoids the ugly critical in FileChooserButton, while
not harming every other ComboBox that doesn’t mess with its model while
popping up (hopefully the vast majority), and it’s very difficult to
imagine a way to check if the active item is /going to/ be hidden later)
Previously, for compatibility with GTK 3.0, we allowed specifying
numbers without units and interpreted them as pixels, even when the CSS
specification didn't.
Remove that now that we can break API.
This reverts commit 4875c689a0.
This was a thinko. Writable is not actually settable from the
application side, but only for the user, from the backend side.
Images with just an aspect ratio, but without a size, should be scaled
to be fully visible in the given area.
But we scaled them to completely cover the given area, which made them
partially invisible.
Reftest included.
gtk_snapshot_pop() => removed
gtk_snapshot_pop_and_append() => gtk_snapshot_pop()
So now there is no way to get a rendernode out of the snapshotting API
until you gtk_snapshot_finish().
... and use it.
The function is a bit awkward because it requires 2 calls to
gtk_snapshot_pop(), but once you accept that, it's very convenient to
use, as can be seen by the 2 implementations.
This is a free-form tab that can contain information about the
system environment. To see it, set GtkAboutDialog::system-information
to a non-NULL value.

We already take ints when setting the translation, so it can't
currently take any other values. Additionally, I was seeing large
costs in int -> double -> int for the rects in
gtk_snapshot_clips_rect(), as all callers really are ints (widget
allocations) and the clip region is int-based.
This change completely cleared a 2% rectangle_init_from_graphene from
the profile and is likely to have nice performance effects elsewhere
too.
The width/height/aspect getters are called a lot, and almost all
callers already verify it from _gtk_css_image_get_concrete_size (),
so just skip these checks.
This means we allocate the collect data with the state, avoiding
an extra allocation. Also, a union means every state object
is the same size and we could reuse the state objects.
Simgle image cross-fade opacity was computed the wrong way, which caused
weird fade-in/out animations, for example in flat buttons.
I messed this up when porting cross-fades to snapshot().
Since the demise of theme engines, we can no longer hit
the case of id >= GTK_CSS_PROPERTY_N_PROPERTIES. So don't
check for this in a very frequently called function.
