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.

Remove the clear allocation flag as it has little impact since there should
be very few allocation per redraw.
Make BLI_memblock_alloc and BLI_memblock_iterstep much more cache efficient
removing them almost entirely from performance profiles.
This will have multiple benefit.
TODO detail benefits (culling, more explicit, handling of clipping planes)
For now the view usage is wrapped to make changes needed more progressive.
There may well be more vertex shaders that need this, but I couldn't find them
in my testing.

This small fix in the GLSL shader seems do to the trick: now smoke won't jitter when using the adaptive domain.
The previous workaround rB3891ad8e0317 is still needed too, i.e. the bug that caused jitter this time was not related to the previous one.
Adding a constant yields quadratic time complexity which can
have quite a big impact on some scenes.
I used the file from T64901 for testing.
In the test file, the time it took to execute `wm_draw_update`
changed from `0.60s` to `0.51s`.

The previous fix 8a6414ed46, resolved selection picking but didn't
work for box/circle/lasso select.
- Add ED_select_buffer_utils.h for general select-buffer operations
unrelated to edit-mesh.
- Circle select still needs to cache select-id's for each update.
There is now a checkbox to enable/disable depth of field per camera. For Eevee
this replace the scene level setting. For Cycles there is now only an F-Stop
value, no longer a Radius.
Existing files are converted based on Cycles or Eevee being set in the scene.

This is to simplify the usage of Volumetrics.
Now it automatically detect if there is any Volumetric material in the
view and allocate the needed buffer if any.
