Carlos Garnacho 77221c18a3 Ensure pixbufs as entry icons get resized 
Entries don't expand vertically if they are given pixbufs larger
than the calculated height for the current font, resulting in
cropped icons, so force the pixbuf to be rescaled so it fits
on the entry allocated size.

/**
* SECTION:gtkentry
* @Short_description: A single line text entry field
* @Title: GtkEntry
* @See_also: #GtkTextView, #GtkEntryCompletion
*
* The #GtkEntry widget is a single line text entry
* widget. A fairly large set of key bindings are supported
* by default. If the entered text is longer than the allocation
* of the widget, the widget will scroll so that the cursor
* position is visible.
*
* When using an entry for passwords and other sensitive information,
* it can be put into "password mode" using gtk_entry_set_visibility().
* In this mode, entered text is displayed using a 'invisible' character.
* By default, GTK+ picks the best invisible character that is available
* in the current font, but it can be changed with
* gtk_entry_set_invisible_char(). Since 2.16, GTK+ displays a warning
* when Caps Lock or input methods might interfere with entering text in
* a password entry. The warning can be turned off with the
* #GtkEntry:caps-lock-warning property.
*
* Since 2.16, GtkEntry has the ability to display progress or activity
* information behind the text. To make an entry display such information,
* use gtk_entry_set_progress_fraction() or gtk_entry_set_progress_pulse_step().
*
* Additionally, GtkEntry can show icons at either side of the entry. These
* icons can be activatable by clicking, can be set up as drag source and
* can have tooltips. To add an icon, use gtk_entry_set_icon_from_gicon() or
* one of the various other functions that set an icon from a stock id, an
* icon name or a pixbuf. To trigger an action when the user clicks an icon,
* connect to the #GtkEntry::icon-press signal. To allow DND operations
* from an icon, use gtk_entry_set_icon_drag_source(). To set a tooltip on
* an icon, use gtk_entry_set_icon_tooltip_text() or the corresponding function
* for markup.
*
* Note that functionality or information that is only available by clicking
* on an icon in an entry may not be accessible at all to users which are not
* able to use a mouse or other pointing device. It is therefore recommended
* that any such functionality should also be available by other means, e.g.
* via the context menu of the entry.
