\brief
|
|
Set the underlying viewport area directly - bypassing what the
|
|
RenderTarget considers to be it's area - thus allowing the view port
|
|
area used for rendering to be different to the area set for the target.
|
|
|
|
\param area
|
|
Rect object describing the area to use in pixels.
|
|
|
|
\deprecated
|
|
This function is deprecated and will be removed or changed considerably
|
|
in future releases.
