Functions for wxGraphicsContext class

A `m:wxGraphicsContext` instance is the object that is drawn upon. It is created
by a renderer using `wxGraphicsRenderer:createContext/2`. This can be either
directly using a renderer instance, or indirectly using the static convenience
`create/1` functions of `m:wxGraphicsContext` that always delegate the task to
the default renderer.

Remark: For some renderers (like Direct2D or Cairo) processing of drawing
operations may be deferred (Direct2D render target normally builds up a batch of
rendering commands but defers processing of these commands, Cairo operates on a
separate surface) so to make drawing results visible you need to update the
content of the context by calling `wxGraphicsContext::Flush()` (not implemented
in wx) or by destroying the context.

See: `wxGraphicsRenderer:createContext/2`, `m:wxGCDC`, `m:wxDC`

This class is derived (and can use functions) from: `m:wxGraphicsObject`
