Replaces GimpPickableInterface's pixel_to_srgb () functions with
pixel_to_rgb(). Now GimpRGB's values should be in the correct
image color space from the beginning of the process.
Some valid PCX/DCX files wouldn't load because the bytes per line
header check can be off by one due to integer division rounding.
This adds 1 to the equation to account for this.
DCX files are containers that store up to 1023 PCX files.
The PCX plug-in is rearranged to allow reading multiple PCX images per
file, rather than assuming there's only one image.
GimpFrame has a property 'line-spacing'. gimp_frame_get_label_spacing ()
tried to access it as 'line_spacing', so it always returned 0.
Fixing the typo should now return the true spacing value.
After testing a bit more, I realized that the thread was constantly re-rendering
the thumbnails, even though I didn't touch the "white-background"
button/argument.
This was not just a completely invisible problem, it actually affected the page
selection (it was very hard to select pages by clicking on them, it was randomly
working, and more often not selecting anything). This is how I realized there
was a problem.
The reason was simply that I was never actually calling g_cond_wait() because of
a first_loop flag I forgot to set.
Note that docs of g_cond_wait() explains that it is possible that "spurious
wakeup" happen. At first I thought I had this issue, which is why this commit
also adds a boolean flag to check after a wakeup, to make sure that I was in the
"condition met" case and not the "spurious wakeup" one.
Even though I realized afterwards the real reason was much more stupid, I still
left this additional check.
Fortunately this issue doesn't seem to affect the 2.10 code. Or to be more
accurate: the continuous render very likely happens there too, yet it doesn't
break page selection interaction with GTK+2 as far as I can see.
Port commit 41f40f530a from gimp-2-10 branch to the main branch:
While at first, the idea of always loading PDF with transparency seemed good
(commit 7aff7e9c70), I realized that a lot of administrative PDF (generated with
text and vector graphics, rather than scans or alike containing raster) actually
have transparency. So now all these documents load with transparent background.
Clearly all the office software are assuming that PDF readers will fill the
background with white.
So add a checkbox to decide whether or not to fill the image with white. I don't
update the PDB procedure. I'll just do this on the main dev branch (while also
updating a bit the code to newer API).
Fortunately I regularly open such PDF documents with GIMP and could witness this
no-transparency expectation before we released GIMP 2.10.34! 😅
As side changes, I also:
* ported file-pdf-load to work with GimpProcedureConfig arguments instead of
GimpValueArray;
* ported the dialog to GimpProcedureDialog and generating as much of it as
possible (except for the page selector/preview, and resolution entries);
* renamed the "pdf-password" argument to "password";
* added the "target", "antialias" and "white-background" procedure arguments.
A few issues which would deserve to be looked at more closely in the future:
* adding "width" and "height" arguments and decide how to handle "resolution";
this will likely be better handled with a new GimpVectorLoadProcedure subclass
to support vector formats in particular;
* shouldn't page selection be handled in a better way? Probably this could be
handled by adding a generic logic in GimpLoadProcedure (as multi-page support
is a common feature across image formats);
* GimpInt32Array arguments ("pages") can't be stored anyway right now.
* the "target" arg should be an enum.
This fixes:

The new function appeared in GLib 2.70 which is our current minimum GLib
requirement, so the replacement is fine.
Generated actions are not necessarily application-wide actions ("app." prefix of
detailed action name). As is the case here, they can be actions specific to a
group only.
With our old code, we needed dummy actions for every submenu. This is not needed
anymore. Actions are only for end menu items (items which actually do something,
not just open a submenu).
Get rid of them all, as well as the code to ignore any action ending with such
suffixes in action-listing pieces of code.
Especially some remnants of when Gimp(Toggle|Radio)Action were not descendants
of GimpActionImpl and had to reimplement GimpAction interface.
Also fixing a few details here and there.
This helps make sure we break circular references as soon as possible when
destroying an action group. I also steal the pointer before freeing objects to
make sure the list is empty immediately and any further signal from the actions
won't affect this group.
Note that it will only work for a model attached to a GimpMenu. In particular,
it won't work for the menu bar set to a GtkApplication with gtk_application_set_menubar().
In other words, it won't work on macOS where we let the OS handle the menu.
Use this for the "View > Zoom" and "View > Flip & Rotate" submenus which used to
display the zoom level and rotation angle. This regression is now fixed.
Though it actually worked in some cases, and failed in others (I have not
figured out which build option exactly makes the format with hole work anyway),
printf manual actually explicitly says:
> There may be no gaps in the numbers of arguments specified using '$'; for
> example, if arguments 1 and 3 are specified, argument 2 must also be specified
> somewhere in the format string.
This explained while it was crashing GIMP (again, only with some build options,
or lack of build options):
> *** invalid %N$ use detected ***
There were 2 possible solutions for this: either ensure that the order number is
always used, but that defeats the purpose of plural localization. Instead I
reorder the argument so that the file name (which must always be shown for sure)
is first in arguments. This way, even if the order number is sometimes omitted
(be it in English or in any language), we avoid the crash.
gimp_rectangle_options_fixed_rule_changed is called when either the
checkbox or the dropdown for Fixed Size is changed.
However, the "fixed-size-active" property was not updated until after
it ran, so the toggle behavior is inverted.
This checks to see if the toggle was changed and updates the boolean
before setting the size field as (in)sensitive.
