These would need to be called something like
WINED3D_CHANNEL_TYPE_UNORM, etc. Those are a bit longer to type, but
we could use a scheme similar to the opcode table in shader_sm4.c to
keep the table readable. (Perhaps "I" -> SINT, "i" -> SNORM, "S" ->
STENCIL, etc.)

Just a thought, but would it make things easier if the channel types
were an array? It would probably make sense for struct wined3d_format
at least to have something like

struct
{
    unsigned int size;
    unsigned int offset;
    enum wined3d_channel_type type;
} channels[4];
