Seems to still build in lol, will check other works to be sure

- Most recent version is in with index buffer support

We already have the convenient degrees() and radians() functions to convert
between angle formats. This commit involves a lot of refactoring here and
there and I may have missed some places where conversions were needed. But
hopefully there aren’t may such places.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

Big FAT pass on windows-warning. It is better now.

scene so that g_scene can be deprecated later.

classes instead of Video.

to show how it can be used.

that 2-year old "temporary Win32 hack".

currently works for images (SDL and GDI+ loaders) and sound samples.

calls so that they take a number of vertices or indexes, not elements.

on Windows if using Visual Studio; if using MinGW, try to stick to the
original main() entry point.

do not open a console at startup.

make sure each .vcxproj file is with its corresponding source code.

personal taste.

it's a bit less confusing.

needs to know about Direct3D headers etc.

the Scene code still breaks Direct3D rendering.

retrieve the constant's register index in the description table. This also
allows us to use a single uniform handle for both the vertex and pixel
shaders in a PS3 Cg program.

cannot used DirectX 10 because my video card only supports DX9, and there
is no compatibility layer. DX11 has feature levels for older hardware so
it would work with a DX9 card, but it's not available for WinXP.

tweak the triangle tutorial to make it shorter.
