The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
This patch will make use of the eDrawType where it was used as a
variable or parameter name. The eObjectDrawType was renamed to eDrawType
as it is also used by `View3DShading.type`.
This is the unification of all overlays into one overlay engine as described in T65347.
I went over all the code making it more future proof with less hacks and removing old / not relevent parts.
Goals / Acheivements:
- Remove internal shader usage (only drw shaders)
- Remove viewportSize and viewportSizeInv and put them in gloabl ubo
- Fixed some drawing issues: Missing probe option and Missing Alt+B clipping of some shader
- Remove old (legacy) shaders dependancy (not using view UBO).
- Less shader variation (less compilation time at first load and less patching needed for vulkan)
- removed some geom shaders when I could
- Remove static e_data (except shaders storage where it is OK)
- Clear the way to fix some anoying limitations (dithered transparency, background image compositing etc...)
- Wireframe drawing now uses the same batching capabilities as workbench & eevee (indirect drawing).
- Reduced complexity, removed ~3000 Lines of code in draw (also removed a lot of unused shader in GPU).
- Post AA to avoid complexity and cost of MSAA.
Remaining issues:
- ~~Armature edits, overlay toggles, (... others?) are not refreshing viewport after AA is complete~~
- FXAA is not the best for wires, maybe investigate SMAA
- Maybe do something more temporally stable for AA.
- ~~Paint overlays are not working with AA.~~
- ~~infront objects are difficult to select.~~
- ~~the infront wires sometimes goes through they solid counterpart (missing clear maybe?) (toggle overlays on-off when using infront+wireframe overlay in solid shading)~~
Note: I made some decision to change slightly the appearance of some objects to simplify their drawing. Namely the empty arrows end (which is now hollow/wire) and distance points of the cameras/spots being done by lines.

Rgression from rBaf4dcc6073fa.
paint_sample_color > imapaint_pick_face uses the the selection buffer
(DRW_select_buffer_sample_point) and to get flat colors [select_id_flat] we
need to be in SCE_SELECT_FACE mode. This was already fine if you had
'Face Selection Masking' turned on, but got colors including lighting
when turned of [select_id_uniform].
There was already an exception in 'select_cache_init' that turns on
SCE_SELECT_FACE for weightpaint, we just need this for texture paint
(vertex paint) as well... Also moved the logic into
select_id_get_object_select_mode.
Note we were also asserting here:
BLI_assert failed: /blender/source/blender/draw/engines/select/
select_engine.c:174, select_cache_init(), at 'e_data.context.select_mode
!= 0'
Note also this is not working correctly for vertexpaint (yet), but has
been discussed in T69752 and there is a solution by @mano-wii in P1032.

But in the future the selection code may also be used in object mode (eg for snapping).
So to avoid using too much VRAM resources, it is good to avoid drawing all objects in the viewport.
The solution was to create an array with only objects that are detected within the selection area.
If the selection operator is modal, objects already detected are not removed from the array until view3d is moved or orbited.
To detect the object, its BoundBox is tested.
Since the Select Engine does not have a dedicated depth texture, whenever a new object is "found" the depth of the objects in the array already drawn is redrawn.

It is easier to deal with private values of the DRW_select engine and gives room for improvement.

`ED_view3d_select_id_read_rect` serves only as a bridge to `DRW_framebuffer_select_id_read`.
Keeping these codes similar only increases the complexity of some functions.

- use DRW_engine prefix for engine types.
- use engine suffix for files that define a draw engine.
- remove engines from include path (they're only referenced once)
