Because as far as I can see the other places that deal with flags use defines
to define them, not an enum type. Specifically, I looked at the
WINED3D_GLSL_SAMPLE_* flags, which have the equivalent job in glsl_shader.c
Besides that, using an enum for OR-able flags seems not quite right to me. If
you have something like
enum flags
{
flag1 = 1;
flag2 = 2;
flag3 = 4;
}
"flag1 | flag3" gives a value(=5) that does not exist in the enum.
