Remove animation loop from ParticlesMaterial and move it to
SpatialMaterial for 3D particles and Particles2D for the 2D case.
Added animation to CPUParticles2D as well as the "Convert to
CPUParticles2D" to the PAarticles2D menu.
This also increases the plugin description TextEdit's height,
so that 3 lines can be viewed instead of just 2 (leaving a few pixels
for the scroll bar).
Reduces visual clutter by hiding pages navigator header and footer in AssetLib if no results are
found or when results fit on one page one page.
Fix for issue #23036
Fix#22724 by adding an Open Resource button
Add a Remove button to each tree item
Remove the old Remove button and its useless code
Adjust columns min width
Remove Resource names and move icons to the left
Add a Resource icon fallback

the tile cursor did not follow the mouse cursor, and the tile grid was displayed wrong,
because the forward_canvas_draw_over_viewport function used the wrong xform and thus its
map_to_world is not the inverse of the mouse interactor world_to_map, making the tiles
draw from 0,0 of the screen instead of 0,0 of the tile map (which is in a different place)

* Orthogonal cameras don't have an FOV that's "near zero". Or zero, or any number of degrees. It's not a measurement of degrees, it's just a fixed width. This comment is more accurate. Also, "terrible" is a better word than "awful" here.
* While I'm editing this file, the "String ortho" variable name could be more intuitive, so I've changed it to "view_mode".
Minor nit-picky changes, I know, but I found it so I may as well improve it.

or more complex issues/hidden bugs where missed values are actually meant
to be handled.

We're not formally using C++11 yet so those trigger compilation warnings
(at least with GCC 5):
./main/input_default.h:122:30: warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11
CursorShape default_shape = CURSOR_ARROW;
^
Note: We may allow those eventually (especially for non-int static const),
but most of current occurrences were inconsistent with all other classes.

Moved the initialisation of origin_enabled up a bit, to be inited before
it's accessed in _init_grid. A step towards cleaner valgrind output and
removes an opportunity for a random occurance of the origin/grid
z-fighting issue.
Also removed unused variable last_grid_snap to avoid later confusion.
At least on en_US QWERTY (and various QWERTY-derived variants)
and fr_FR AZERTY, "+" is an indirect key obtained by pressing
"Shift" + "=", so using "=" in the binding makes it easier to
access.
It doesn't work this way on other layouts like de_DE QWERTZ though,
but since 'script_editor/zoom_in' also uses KEY_EQUAL, setting
the same for consistency.
Fixes#22067.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
It's shared by both 2D and 3D particles (+ CPU ones), so it makes sense
to have as a common resource. It also allowed to disable compilation of
Particles (3D) when using 'disable_3d'.
Also cleaned up includes in SpatialEditorGizmos and some other places,
as well as dropped dead code in material_editor_plugin.cpp.
This also changes the uppercase/lowercase/capitalize shortcuts
to Shift+F4, Shift+F5 and Shift+F6 respectively to avoid conflicts
with the new Find Next shortcut.
This closes#21612.
```
Play Scene Command+R (no change)
Replace... Command+R => Option+Command+F
Find Function... Option+Command+F => Ctrl+Command+J
```
On macOS Option+Command+F is commonly used for Find and Replace so use
it instead to avoid conflicting with "Play Scene"
And as Option+Command+F is currently used by "Find Function..." rebind
the latter to Control+Command+J which is the Xcode shortcut for
"Jump to Definition"
Fixes#19817
Selecting instanced scenes still doesn't work properly because gizmos are not being added to instanced nodes.
I will probably work on fixing all the shenanigans around selection, but that will take some time.
This part of the code should work better for the moment.
Properly draw navigation and oclusion polygons for SINGLE type tiles. Fixes#21398
Add some checks for TileID validation before accessing to it's properties. Fixes#21397
Fix 'Keep inside region' snap option for tiles with SINGLE_TILE mode. Fixes#21402
Restore hability to asign/unasign an script to a tileset. Fixes#20886
This is caused by GitHub not publishing a Content-Length header in
all cases (it only does so if the file was requested recently),
which in turn made `String.humanize_size()` try to humanize a size of
-1 byte (as returned by HTTPRequest when no Content-Length
is contained in the response).
This crashed the editor due to a division by zero.
This closes#21200.
