Is there a plugin (or high speed script-fu) that would allow me to enter
a math expression and from it create the pixel data also given a
'viewport range'.

## Advertising

XMin: -1
XMax 1
YMin -1
Ymax: 1
UseGraient: no
Expr: red=sin(2*pi*x*y)/2+0.5;green=...,...
or
UseGradient: yes
Expr: offset=sin(2*pi*x*y)
Or something like that. I imagine a script-fu could be done that could
take the viewport, gradient, and expression and somehow execute the
expression and plot the pixels, but it seems like script-fu would be
somewhat slow. I've created my own expression evaluation library which
would easily provide all the math support I need, but don't know much
about making GIMP plugins and since I'm only on Windows now I've had
problems trying to compile glib/gtk under msys/mingw, plus it is C++
except an older version which is C.
