Line art now uses global index for vertices but needs to have
local index in order to do correct weight transfer.
|

Two main fixes:
- Split tiles only when we are more sure that it will improve distribution.
- Discard edges and chains that are not gonna be used afterwards before chaining.
This speeds up the whole process and also eliminates unnecessary tile splitting.

- Use uintxx_t for all 8/16/64 bit integer types.
- Removed prepend_edge_direct thingy which is no longer needed in current edge iterator model.
- Minor code path adjustments like only copies view vector when necessary etc.
- Correctly handle ies==NULL in edge cutting function.
- White spaces and comments etc.

This patch does code clean ups in `LineartRenderBuffer` because it's

This change allows the chaining function to select edges
from the same contour loop first, thus reduced rouge chain
connections (connected different objects instead of chaining
inside the same object first) and improved chaining quality.
This patch also included the default value change for chain
split threshold (Now don't split by default to make initial
result as smooth as possible)

This fixes the smooth tolerance feature in master where sometimes you could
get over simplified chains and lose the shape it's supposed to be originally.

Instead of splitting it at each occlusion change, it tolerates short segments of "zig-zag" occlusion incoherence and doesn't split the chain at these points, thus creating a much smoother result.

This option allows the edge to end right at the border
instead of extending beyond.
Useful when having multiple camera setup where you
want the border to be clean.
Also moved overscan option down inside "Composition" sub panel
so it makes more sense.

It caused some chaining errors when used in combination with image space
chaining. After some internal discussion, we realized it is not
useful as chaining in image space essentially does the same thing.

This adds the LineArt grease pencil modifier.
It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.
This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.
These lines can then be baked and edited as regular grease pencil lines.
