This minor upgrade adds some fixes and changes that are a bit more than just patches. The text now
has subchapter headings to help readers browse content and get a bit more context. We're introducing
new type aliases point3 and color for vec3 to better indicate the underlying mathematical
types of parameters and variables. Overall, a bunch of small improvements that we'd recommend
adopting, but may warrant comparison with any current projects.

(#434)This major release marks an overhaul of the entire series, moving from a primarily PDF format to a web accessible format using Markdeep (https://casual-effects.com/markdeep/). This represents a huge overhaul to the contents, particularly around source code blocks in the text, mathematical typesetting and source-code cleanup.

This release tackles the following key themes:
Establishing a common build system for the three projects. We chose CMake for its broad support for multiple platforms, as well as multiple build tools and IDEs. This change includes a reorganization of the project source files, and unifying a lot of code across projects.
A major upgrade of the project source code, addressing a number of large changes that we had deferred for later.
A number of larger changes to the book content, refining some approaches and ideas, and addressing some areas in the text that needed improvement.
Following this release, we expect to switch to a much more incremental approach, mostly with patch-level (fix) changes and some minor-level (addition) changes.
