---------------------------------------------------------------

I agree there is a need to open the render destination even for bitmap generation functions.
this new patch adds a call to renderImage with an additional destination parameter and a member
defaultDestination in the style of subsamplingAllowed to PDFRenderer.
The initial value of defaultDestination is intentionally null as null represents the default
behaviour: EXPORT for renderImage and VIEW for renderPageToGraphics
