Fix: weight painting operated only for selected vertices in edit mode.
We only need this in case vertex selection is enabled.

remove vertex selection check for weight paint mode so you can paint `through` the mesh.

also made the wire draw without depth masking when the depth check is off, similar to mesh editmode drawing, nice hint about whats going on.

patch [#33331] Time To Start Moving To Stdbool
by Lawrence D'Oliveiro (ldo)

so BKE_utildefines.h allows use of C99's bool type and true/false.

currently scons wont try to use stdbool.h, and works as if its never found.

make wight-paint-through feature work in face select mode. (still WIP, relies on selection flushing which currently ensured).

fix for long standing annoyance with weight-paint mode selection.

There was no selection flushing when faces or verts were selected, this allowed incorrect selection states like selected face with unselected vertices.

add flush commands to paintface_flush_flags() and paintvert_flush_flags()

Added MOUSEPAN (the trackpad event) to control propertional size while transform.

There's many hardcoded scrollwheel events in Blender for this, and with new proper
analog trackpad handling I'll try to find good remapping for most cases.

Add a warning to enum props' items parameter, to *never* use a generator as value for this param! It works in most cases, but in some it leads to an empty set of values for the enum (see [#33716]), and it's not an easy bug to track down!

Highlight currently rendering tiles

This commit implements highlight of tiles which are being currently
rendered for both Blender Internal and Cycles (and should be possible
to use it for other external engines as well).

Couple of implementation details:

- Added one extra boolean flag to render engine which should be set
  to truth if render engine wants to highlight tiles. If so, property
  use_highlight_tiles should be set to True.

- Render Part's ready boolena was changed by status enum, which could
  be NONE, IN_PROGRESS and READY. All render part with IN_PROGRESS
  status will be highlighted in image editor.

- For external engines render part's status is filling in automatically.
  Initially all render parts has got NONE status, then one external
  engine acquire render result, corresponding part will change status
  to IN_PROGRESS. As soon as render result is finished, corresponding
  render part will change status to FINISHED

  This should make it easy to highlight tiles for other engines as well.

Further trackpad work:

When trackpad swipes don't convert to ScrollWheel steps anymore, several hardcoded
wheel events need to support swipe too.

This adds swipe support to:
- Menu item scroll
- Search item scroll
- ALT + number/slider/swatch values

The amount of old style scroll "clicks" is calculated based on how trackad is
being mapped to move a mouse pointer. Move it one widget unit = 1 click.

The swatch option applies trackpad swipe motion in analog way.

Intent to fix windows not compiling after r53480.

Looks like _Bool is also a type in std (at least with msvc), so the 'typdef bool _Bool;' generates a name collision... Now using _BLI_Bool as placeholder instead.

Bug fixes, own collection.

While examining icons, I noticed material icons were too dark.
It appeared a lot of bad hacks were added for colormanagement in preview render.

Removed them all, and things look smooth (yes, color management is OK!).

However! It is now very clear that Procedural Textures miss getting inverse
color managed in render - a reason why they show so bright washed out, already
since introduction of Color Management in Blender.

Try render a plane with linear black-white blend, shadeless!

Todo: add colormanaged procedurals (optional).
