/** Helper template to handle XIntegerBitmap method forwarding to
BitmapCanvasHelper
Use this helper to handle the XIntegerBitmap part of your
implementation.
@tpl Base
Base class to use, most probably one of the
WeakComponentImplHelperN templates with the appropriate
interfaces. At least XIntegerBitmap should be among them (why
else would you use this template, then?). Base class must have
an Base( const Mutex& ) constructor (like the
WeakComponentImplHelperN templates have).
@tpl CanvasHelper
Canvas helper implementation for the backend in question
@tpl Mutex
Lock strategy to use. Defaults to using the
OBaseMutex-provided lock. Every time one of the methods is
entered, an object of type Mutex is created with m_aMutex as
the sole parameter, and destroyed again when the method scope
is left.
@tpl UnambiguousBase
Optional unambiguous base class for XInterface of Base. It's
sometimes necessary to specify this parameter, e.g. if Base
derives from multiple UNO interface (were each provides its
own version of XInterface, making the conversion ambiguous)
@see CanvasBase for further contractual requirements towards
the CanvasHelper type, and some examples.
