Descent 3: Piccu Engine

This is a new engine for Descent 3, from the initial 1.5 source code release. It incorporates almost every change from InjectD3, among many more.

At the moment, this includes the following features:

Centered window mode
Scaling in window and fullscreen mode
Fullscreen which does not change desktop settings (multi adapter support forthcoming)
New mouse code
Adjustable FOV, with automatic expansion for widescreen
Missing features in OpenGL restored, including specular highlights and the ability to control mipmapping
Cockpit actually works in widescreen, unlike InjectD3
Faster iteration when many missions are present.
Smoother UI (FPS limit raised to 60)
OpenAL sound system with no crackling and environment reverb support.
Many bugfixes

Building

At the moment the build environment is only set up for Windows, but I hope to change this shortly. Building on Windows is done with CMake.
