Shroud, access ProjectedCellLayer by array index over PPos index.
Performance improvement. Avoid the multiple PPos to array index
conversions in the same method call by calculating the cell
layer index once.
Background:
`Shroud.Tick` and `ProjectedCellLayer.Index(PPos puv)` shows up
in profile reports as one of the most expensive methods
(9% of CPU time).
In `Shroud.Tick` calls `ProjectedCellLayer.Index(PPos puv)` multiple
times for the same or different cell layers of the same dimension.
Improvement:
Benchmark results show an 0.5ms mean improvement in tick
time and 0.3 improvement in render time -
on a replay map of 1.12 min of play at max speed.

Shroud.touchedCount to avoid Tick updates if no cells touched.
Avoids iterating over all map cells of the `touched` cell layer.
Tick time improvement of 40%+ - during at least the first two
minutes of gameplay.
During the first minutes of a game - out of every 1000 ticks
only 10-100 result in the Shroud - of any player - to be touched.
For certains player types (Neutral, Creep) less Shroud updates
are expected throughout a complete game.
Throughout a complete game human/AI players can also have no
Shroud touches during certain Ticks.
All targetlines can now be set to a custom color in yaml or set to be invisible.
All automated behaviours including scripted activities now have no visible target lines.
- Distinguish between missing sequences and missing sprites
- Lint default sequences as well as maps
- Improved performance
- Correctly handle null images
- Removed implicit pip definitions and IPips interface.
New decoration traits have been added to render them.
Pip types are no longer hardcoded in OpenRA.Game.
- Decoration rendering is now managed by SelectionDecorations(Base),
which allows us to remove assumptions about the selection box
geometry from the decoration traits.
- RenderNameTag has been replaced by WithNameTagDecoration, which is
an otherwise normal decoration trait.
- Unify the configuration and reduce duplication between traits.
- Removed hardcoded references to specific selection box renderables.
- Remove legacy cruft.
