clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

Fix tonemap exposure not being taken into account by sharpening
The same fix as FXAA was applied to the CAS filter.

Clamp negative colors regardless of the tonemapper to avoid artifacts
Color artifacts could be visible when using negative lights with the
Filmic and ACES tonemapping operators, as these did not clamp negative
colors.

Add support for contrast-adaptive sharpening in 3D (GLES3 only)
This is an older, easier to implement variant of CAS as a pure
fragment shader. It doesn't support upscaling, but we won't make
use of it (at least for now).

The sharpening intensity can be adjusted on a per-Viewport basis.
For the root viewport, it can be adjusted in the Project Settings.

Since `textureLodOffset()` isn't available in GLES2, there is no
way to support contrast-adaptive sharpening in GLES2.

Add a debanding property to Viewport for GLES3
It can be enabled in the Project Settings
(`rendering/quality/filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).

As a result, it should be enabled only when banding is noticeable enough.

Since debanding requires a HDR viewport to work, it's only supported
in the GLES3 backend.

e6a860deb6 tonemap.glsl: Ensure color parameter of tonemap_reinhard() is positive
Color values can become negative in the case of negative lights which
leads to undesired behaviour.

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.

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.
