[gnome-db] GDA_VALUE_TYPE_IMAGE

[Rodrigo Moya <rodrigo gnome-db org>]

HI

I am going to add support for images in GdaValue's, which will then be
shown in the grid widget, as GdkPixbuf's.

The easiest way to convert the data in the GdaValue to a GdkPixbuf is to
have providers return the image in raw data, which can then be converted
to a pixbuf easily.

Does this sound ok for all providers?

cheers
