-input now correctly works when using viewport scaling
-added function to get areas/bodies in given point
-added function to get space state directly from world
Added support for 2D shadow casters.
*DANGER* Shaders in CanvasItem CHANGED, if you are using shader in a
CanvasItem and pull this, you will lose them. Shaders now work through a
2D material system similar to 3D. If you don't want to lose the 2D
shader code, save the shader as a .shd, then create a material in
CanvasItem and re-assign the shader.
I could reproduce the crash described in #1284 only with 32bits versions of godot.
The test scene contains a Plane collision shape, and a kinematicsbody with a Sphere collision shape.
The crash occurs into `CollisionSolverSW::solve_distance_plane()` on line 299 when `p_shape_A` is a `PlaneShapeSW` object and when `p_shape_B` is a `MotionShapeSW` object, because `int support_count;` is not initialized by default, and because `MotionShapeSW::get_supports()` does not change `support_count` once passed as referenced parameter, and if the default value of `support_count` is greater than the length of `supports[16]`.
I don't know if it is the good way to fix it because i'm not skilled ennough with the physics server inner working, but this fix prevents the crash and the test-scene seems to work correctly.
-=-=-=-=-=-=-=-=-=-
-Moved drawing code to a single function that takes linked list (should make it easier to optimize in the future).
-Implemented Z ordering of 2D nodes. Node2D and those that inherit have a visibility/Z property that affects drawing order (besides the tree order)
-Removed OpenGL ES 1.x support. Good riddance!
-Working area is bigger now, solves #1148
-Using Position now works, fixes#1141
-RGB ops now work, fixes#1139
-Missing bindings to GraphEdit and GraphNode added
-Shader Graph Editor Shows errors on cyclic links and missing connections
-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-Removed "density" property
-Added instead more flexible "angular damp" and "linear damp"
-Added ability to override angular and linear damp in rigidbody
-Added gravity scale option rigidbody
Test well and iron out bugs, when it works the same will be moved to 3D
-work in progress new graph system (will replace current one)
-crash fix in s3m loader (out of bounds acess)
-fixed vbox overriding of separation (fixes empty line between section tabs)
