plug-ins: Fix ImageMap resize bug in GTK3

Browse source 
Resolves #10530.

In GTK2, setting a window's scrollbar policy to GTK_POLICY_NEVER
hid the scrollbars. In GTK3, this also makes the window automatically
resize to fit the contents. Since ImageMap displays the full drawable
with no scaling, this caused the plug-in window to be very large for large
layers.
GTK_POLICY_EXTERNAL in GTK3 works the same as the GTK2 version of
GTK_POLICY_NEVER, so using it instead fixes the problem.
The default width and height magic numbers were also replaced with
constants.
