[Gimp-developer] Maximum new image size slightly different when trying to create a new large image

[Cristian Secară <liste secarica ro>]

Suppose I have the Maximum new image size set to 128 GiB. I try to create a new image with ridiculous size, 
say 21920×21080 px.

A popup message tells me that "You are trying to create an image with a size of 4,3 GB. An image of the 
chosen size will use more memory than what is configured as "Maximum new image size" in the Preferences 
dialog (currently 134,2 MB)."

The same happens if I set the maximum to 256 MiB -> the dialog says "... (currently 268,4 MB)."

Where from comes that difference in numbers ? Even if I calculate 256*1024 it gives 262144 (let alone that I 
see no reason for this)
