b835868067 Create shadow_vec for altering shadow computation 
In 2.1 and 3.0, light_vec could be modified for altering shadow_computations.
But it broke shadows when rotating light. shadow_vec would do the same, but without breaking
shadows in rotated lights if not used.

Add inverse light transformation to shadow vec, so it's not affected when rotating lights;

Added usage define for shadow vec.

For shadow vec working properly when rotating a light, it's needed to multiply it by light_matrix normalized. Added usage define in order to don't do that if shadow_vec not used.

aa3ef8893b Removed clamping of the Linear tonemapping when KEEP_3D_LINEAR 
Changed the behaviour of the Linear tonemapping operator to not clamp to [0, 1] range
in the case when KEEP_3D_LINEAR is defined. This allows to render values > 1.0 in
floating point texture targets (via Viewport) for further processing or saving high
dynamic range data into files. This only works when no color conversion is active.

8fb80788df changed the constant scale of cube_normal to -1.0 instead of -1000000.0; this fixes a rendering issue on oculus quest and does not change the computation as the vector is normalized afterwards. 
Adapted the comment above the code to reflect the change made as it already mentioned that z could be set to 1.

02ea99129e Adding a new Camera Server implementation to Godot. 
This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server.
Other parts of Godot can interact with this to obtain images from the camera as textures.
This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.

Improve SSAO performance and quality 
This decreases the number of samples significantly, leading to a
notable performance increase with only a very slight loss in
visual quality.

This also tweaks the default SSAO settings to use 3×3 blurring,
which makes noise patterns much less visible.

4226d56ca9 Style: Enable clang-format on GLSL shaders 
As of clang-format 6.0.1, putting the `/* clang-format off */` hint
around our "invalid" `[vertex]` and `[shader]` statements isn't enough
to prevent a bogus indent of the next comments and first valid statement,
so we need to enclose that first valid statement in the unformatted chunk.

fd166d6fda Partially undo #11807. 
Specular light at zero roughness needs some discussion. Until we do that, this fixes #12309.

06fcbe0092 Don't add clearcoat BRDF to specular light as-is. 
BRDF needs to be multiplied with N.L, the incoming light and attenuation. Also specular_blob_intensity should affect clearcoat.

cb0bf1edea Rename Schlick GGX to GGX. 
Schlick's approximation and GGX are orthogonal concepts.

Furthermore, it's usage so far has been inconsistent: we don't even use it with anisotropic SchlickGGX, and Burley (Disney) diffuse does use it while its name doesn't indicate it.

The use of Schlick's approximation in Burley and GGX is an implementation detail and doesn't need to be reflected to the namig.

9324555998 Fix the condition when specular light calculation is avoided (should be roughness == 1). 
Also avoid calculating diffuse light calculation when metallic == 1, and test against clearcoat's own parameter to check whether to do clearcoat.
