Allocating a lot of colors

[Lokesh Setia <lsetia78 yahoo com>]

Hello,

I'm writing a Image processing application, in which I need to show 
intermediate results of my calculations as an image in a window, nothing 
more.  

First of all, I will like to ask whether drawing_area widget with a 
backing pixmap is the best choice for this?  I will have to call 
gdk_draw_point{s}( ) in this case I guess
Second, when the image changes (it does after every 50 msec), colors may 
need to be allocated/deallocated. Doing  gdk_colormap_alloc_color() in a 
loop seems to be a grossly inefficient way of doing this.  Is there any 
other option?  BTW, since the application is only meant for internal 
use, I do not have to make it work for 8-bit displays if it helps in any 
way :)
Regards,
Lokesh
