More than 2000 lines of code less in app/, instead of
if (instance->member)
{
g_object_unref/g_free/g_whatever (instance->member);
instance->member = NULL;
}
we now simply use
g_clear_object/pointer (&instance->member);
Nobody has them anymore, and they are deprecated in GTK+ 3.x. This
also fixes all conflicting mnemonics except those I missed, but we can
fix them now.
Adds an icon-pixbuf property to GimpViewable that is used for a default
implementation of new_pixbuf.
Extend gimp_icon_picker to allow the user to pick non-stock icons for tool
presets (or any other class derived from GimpViewable). Icons can come
from any file GdkPixbuf can load or from image data on the clipboard.
