Hi there,

the shade.rel.sh script can be fixed as
follows:

Replace $esres and $nsres with ewres() and nsres().

Then update some numbers:

diff shade.rel.sh shade.rel.sh.orig
67c67
<  aspect=if(x||y,if(a,a,360.)), \\
---
>  aspect=if(x||y,if(a,a,360)), \\
69c69
<  if(cang < 0.,0.,100.*cang))
---
>  if(cang < 0,0,100*cang))

Ciao
