gEDA-dev: Bug fix for embedded pictures not working

[Peter Clifton]

Hi Ales,

You might want to cherry-pick:

commit 1f336cc81195dadaffd4bbec17e8a40950b7935b
Author: Peter Clifton <pcjc2 at cam.ac.uk>

    Simplify test to call gdk_init() in o_read_picture()
    
    Avoids testing a GtkWidget pointer in TOPLEVEL variable setup by gschem or
    gattrib. Instead, just ensure we call gdk_init() at least once. If gschem
    or gattrib already did, its not a problem as repeated calls aren't harmful.


I was trying to test my refactoring of the picture code, and noticed
embedded pictures didn't work. Due to reading off the end of a memory
buffer, the bug(s) could cause a segfault due to invalid reads.

Regards,
