move palettes from GDI heap to system heap

[Warren_Baird at cimmetry.com]

ChangeLog:

     Allocate palette objects on the large heap instead of the GDI heap
     to avoid GDI heap saturation.

Description:

     Since a palette can theorically be infinite there's a risk of filling
     up the small size GDI heap if we allocate palette objects on it. We
     encountered that problem when playing some Windows metafiles that
     contained multiple fairly large palettes.
