// eke-eke says GX_Begin() costs 3 bytes (u8 + u16)
// According to my research:
// GX_Position3f32() is 12 bytes (f32*3)
// GX_Normal3f32() is 12 bytes (f32*3)
// GX_Color3f32() is actually 3 bytes ((f32 -> u8) * 3)
// GX_TexCoord2f32() is 8 bytes (f32*2)
// GX_End() seems to cost zero (there's no actual code in it)
// Size -must- be multiple of 32, so (12*24) + (12*24) + (3*24) + (8*24) + 3 = 843
// Rounded up to the nearest 32 is 864.
// NOTE: Actual size may be up to 63 bytes -larger- than you calculate it to be due to padding and cache alignment.
