Copy over the implementation of _gtk_menu_shell_activate
so that C4013 warning/error (aka gcc's "implicit
declaration of ...") can be avoided when compiling with MSVC
This is in response of the changes for bug 554057 in commit
5f55c42047
We can't really know the client side keymaps, so we use the keysym
as the hardware keycode (essentially claiming to have a keyboard with
one key for all possible keysyms). This is not ideal, but its hard to
do better with no knowledge of the client side keyboard mappings.
(And html keyboard events suck badly...)
We're using the noVNC keyboard even handling model (and some of the
code with permissions). This means we combine data from keydown and
keypress to figure out the translated keysyms according to the keyboard
layout at the users machine.
This symbol needs to be exported for GDK (Win32) so that the
runtime checks for Win32 backend usage can be done on
MSVC-compiled versions of GTK+ too.
I did not add the corresponding symbols for the other backend
though-they are probably exported automatically by GCC AFAIK.
This is done to make commit
9db4accf9c
work on MSVC
Otherwise, we end up doing maximal work with minimal effect, and
bring the X server to 100% CPU. Note that this makes spinner widgets
look really unclear, but they really have to be changed to adapt
to enable-animations == FALSE at the widget level.
The button is what draws the background/frame outline of the combobox,
and padding is defined as the spacing *inside* the widget between the
border and the content.

When the combobox is in menu mode, the right padding of the togglebutton
inside, should be allocated to its rightmost children, which is the
arrow.
