imageobj pasteimage transparency no longer works

Description 

As of 4.0, pasteImage no longer works with transparency because the second
parameter is the index of the color object to use as the 'transparent' color. 
With the switch to a 24bit color model internally, this function should be
updated to take either a colorobj or some color identifier (0xrrggbb?).

Fixed in MapServer 4.1 (CVS).  Let me know if this is really needed in 4.0.x.

PasteImage() now takes a hex color value (e.g. 0xrrggbb) for the transparent
color instead of a color index.

Also note that the function works only with the source image in 8 bit image
formats (GIF/PNG) and won't work with PNG24 (I don't think the target image
format matters).  Anyway this function is a hack so I don't think it needs to
work with 24 bits PNG.
