Sandia National Laboratories recently changed management from the

This commit converts `Canvas` from an abstract class to a concrete
class by converting the pure virtual methods to empty/default
implementations. It provides an implementation for `Canvas::AddLine`
using Bresenham's line drawing algorithm.

This commit solved z-fighting issues with two changes:
- A small offset, proportional to distance between near and far planes, is
applied in camera space to the edges.
- The minimum screenspace offset is increased as well for the same reason.
A new test case is added for uniform grids.
Additionally, the line plotting algorithm is changed to round off the
edge endpoints to fill in empty pixels seen on uniform grids.

This change adds a option via `SetIsOverlay` which causes the
`MapperWireframer` to use the existing depth buffer instead of
generating a new one.
This change refactors the line color blending to
retain the alpha value separately instead of pre-multiplying it.

The algorithm is parallelized using a custom Mapper and Canvas class.
It is parallelized over the expected pixels that will be colored,
blending with any previous color value. This does not use the depth buffer
and hence will naively overrwite all pixels while drawing a line segment.
