This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.
This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.
As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.
OK, these changes effect a lot of file, I suggest everyone updates ASAP:
Removal of many files from project.
Removal of meanless Gr_bitmap_poly variable.
Removal of glide, directdraw, software modules all links to them, and all code specific to those paths.
Removal of redundant Fred paths that arent needed for Fred OGL.
Have seriously tidied the graphics initialisation code and added generic non standard mode functionality.
Fixed many D3D non standard mode bugs and brought OGL up to the same level.
Removed texture section support for D3D8, voodoo 2 and 3 cards will no longer run under fs2_open in D3D, same goes for any card with a maximum texture size less than 1024.
