Browse Source 
```
      :gif0 (new 'static 'gif-tag64
        :nloop #x4
        :eop #x1
        :pre #x1
        :prim (new 'static 'gs-prim :prim (gs-prim-type tri-strip) :iip #x1 :tme #x1 :fge #x1 :abe #x1)
        :nreg #x3
        )
      :gif1 (new 'static 'gif-tag-regs :regs0 (gif-reg-id st) :regs1 (gif-reg-id rgbaq) :regs2 (gif-reg-id xyzf2))
```
instead of
```
:gif (new 'static 'array uint64 2 #x303e400000008004 #x412)
```
