The new Quick Filter Files behaviour since 8b47e26 had not been implemented,
so this implements it and makes it an editor hotkey instead of a menu entry.
Fixes#7582.
Made sure files in core/ and tools/ have a proper Godot license header
when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h}
to rect3.{cpp,h} and class_db.{cpp,h} respectively.
Also added a proper header to core/io/base64.{c,h} after clarifying
the licensing with the original author (public domain).
It supports unlimited width, color gradient, texture and some geometry
options for joints and caps. Also transparency without artifacts
(provided that line joints aren't too sharp).
-An action being requested to the user in present tense: (ie, draw, gui_input, etc)
-A notification that an action happened, in past tense (ie, area_entered, modal_closed, etc).
This means that each time this scene is instanced, the resource will be unique!
As such, thanks to this, the following features were implemented:
-ButtonGroup is no longer a control, it's now a resource local to the scene
-ViewportTexture can be created from the editor and set to any object, making ViewportSprite and other kind of nodes obsolete!
-Changed SectionedPropertyEditor to support this
-Renamed Globals singleton to GlobalConfig, makes more sense.
-Changed the logic behind persisten global settings, instead of the persist checkbox, a revert button is now available
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!
* Added the option to set hide on item selection. Usable in GDScript and from within the source code when you want to specify popup menus you don't want to close immediately when selecting an item
* Renamed getter from get_ to is_, fixed parent/child behavior, renamed bool variable to match most code and added ADD_PROPERTYNO to save some memory
