/**
* katze_property_proxy:
* @object: a #GObject
* @property: the name of a property
* @hint: a special hint
*
* Create a widget of an appropriate type to represent the specified
* object's property. If the property is writable changes of the value
* through the widget will be reflected in the value of the property.
*
* Supported values for @hint are as follows:
* "blurb": the blurb of the property will be used to provide a kind
* of label, instead of the name.
* "file": the widget created will be particularly suitable for
* choosing an existing filename.
* "folder": the widget created will be particularly suitable for
* choosing an existing folder.
* "uri": the widget created will be particularly suitable for
* choosing an existing filename, encoded as an URI.
* "font": the widget created will be particularly suitable for
* choosing a variable-width font from installed fonts.
* Since 0.1.6 the following hints are also supported:
* "toggle": the widget created will be an empty toggle button. This
* is only supported with boolean properties.
* Since 0.1.8 "toggle" creates GtkCheckButton widgets without checkmarks.
* Since 0.2.0 the following hints are also supported:
* "font-monospace": the widget created will be particularly suitable for
* choosing a fixed-width font from installed fonts.
* Since 0.2.1 the following hints are also supported:
* "application-TYPE": the widget created will be particularly suitable
* for choosing an application to open TYPE files, ie. "text/plain".
* "application-CATEGORY": the widget created will be particularly suitable
* for choosing an application to open CATEGORY files, ie. "Network".
* "custom-PROPERTY": the last value of an enumeration will be the "custom"
* value, where the user may enter text freely, which then updates
* the property PROPERTY instead. This applies only to enumerations.
* Since 0.4.1 mnemonics are automatically stripped.
* Since 0.2.9 the following hints are also supported:
* "languages": the widget will be particularly suitable for choosing
* multiple language codes, ie. "de,en_GB".
* Since 0.3.6 the following hints are also supported:
* "address": the widget will be particularly suitable for typing
* a valid URI or IP address and highlight errors.
* Since 0.4.0 the following hints are also supported:
* "days": the widget will be particularly suitable for choosing
* a period of time in days.
*
* Any other values for @hint are silently ignored.
*
* Since 0.1.2 strings without hints and booleans are truly synchronous
* including property changes causing the proxy to be updated.
*
* Since 0.2.1 the proxy may contain a label if the platform
* has according widgets.
*
* Return value: a new widget
