Regenerating bindings

In order to update raylib-d to work with a newer version of raylib, the headers must be regenerated with dstep.

Three modules should be regenerated: raylib, raymath and rlgl.

Run the following command from the raylib/src directory. Note: path/to/raylib-d should be the path to the raylib-d repository that you have on your system.

dstep raylib.h raymath.h rlgl.h -o path/to/raylib-d/source/raylib --space-after-function-name=false --skip Vector2 \
    --skip Vector3 --skip Vector4 --skip Quaternion --skip Matrix --skip Rectangle --skip RL_MALLOC --skip RL_CALLOC \
    --skip RL_REALLOC --skip RL_FREE

Note: we're skipping a couple symbols because we define them manually in raylib_types. We also skip memory functions because they only have effect when compiling Raylib in C.

Finally, the raylib.h file will export as raylib.d, but it should be moved to raylib/package.d.

After you regenerate them, they won't be ready to use yet. We need to add module declarations and imports at the top of each module:

module raylib;

public
{
    import raylib.rlgl;
    import raylib.reasings;
    import raylib.raymath;
    import raylib.raymathext;
    import raylib.raylib_types;
    import raylib.binding;
}

module raylib.raymath;

import raylib;

module raylib.rlgl;

import raylib;

Additionally, each of those modules will have an automatically generated extern (C): line. We need to find it and edit it to extern (C) @nogc nothrow:.

This should be enough. Run dub test and see if it compiles.
