Fix for GPencil and Cycles Render draw type. GPencil objects were only
shown when overlays were turned on. The cause of this is an
optimization we did to not populate any draw engine when an
external renderer was used with overlays turned off.
This will check if there is any visible GPencil object in the scene. if
so it will still perform the loop.
`DEG_id_type_any_exists` can check if any object of a certain type_id is in the
result. This check is also being used to check if there are any
visible grease pencil objects as a precheck in `DRW_render_check_grease_pencil`.

three issues here:
- when curves had multiple nurbs, the active vert is per nurb
[curve_create_edit_data_and_handles() wasnt taking that into account]
- code could go wrong when points where hidden
- upon selection, tag curve ID_RECALC_COPY_ON_WRITE for batch cache

The calculation of the mix color was not using the bottom color when the alpha was lower than 1.0.
Also added clamp code to avoid values outside valid ranges.
When XRay is turned on the mesh analysis did not draw correct. This
change won't draw the mesh analysis overlay when xray is turned on.
In terms of giving the user a visual feedback of this limitation we
render the overlay options inactive.

- Make edges darker in vert & face select mode (making more
contrast to not loose the topology). Downside is less select
edges visibility in vertex mode. But I'm confident that it's not
as painfull as it seems.
- Make select faces less saturated to have more color contrast
between select faces and edges.
- Make unselected faces white to increase contrast with faces and
edges. The brightening is negligeable for bright surfaces and
help readability on darker surfaces. Reminder that if the faces
overlays are too distracting (i.e: uv mapping, or texturing) they
can be toggled off in the overlay panel.

When viewport samples are set to 1 simple scenes with volumetrics crash.
EEVEE volumetrics needs to init the post processing buffers. With recent
changes the need for post processing buffers are known after the cache
init. But they are constructed before the cache init. This lead to null
pointers.

This is too generic flag, and it might be used by anything, starting from
changes in transform ending with changes in ID properties.
The check here is to be as specific as possible. If that is not possible
the decision must be documented.

When using texture drawing the material alpha was not set correctly, It
used the `shading.xray_alpha` as this was the default set in the forward
renderer.
The unit system is designed for displaying and editing and not for
rendering. Eevee, Workbench and GPencil used these settings to convert
the focal length and sensor size to world units. Making depth of field
render differently with Cycles.
For now we will remove the scale in the draw engines to match cycles,
until we implemented a camera parameters specific scale.

When using FXAA when rendering to an image the alpha channel was not
correct what lead to visual artifacts.
These artifacts come from the FXAA function that overwrites the alpha
channel with the original Luma of the texel. In the shader this can be
turned on or off. But at the end it always overwrites the alpha with the
luminance.
We didn't use this feature, but the alpha of the resulting pixel still
contained the luma value what lead to render artifacts.
By overwriting the alpha channel with the original alpha we remove these
artifacts.
