VCLCanvasSize returns (0, 0) if VCLCanvas has not been initialised

I found an oddity in code where I accessed VCLCanvasSize before VCLCanvas. Since the VCLCanvas is lazily created on demand, this scenario leads to GetVCLCanvasSize accessing fVCLCanvasSize before it has been initialised. I worked around this by making sure that I access VCLCanvas before VCLCanvasSize, but I think that this protection should be implemented inside SynPdf.

Thanks, that's exactly what I was hoping for. I can now remove my workaround.

Thanks for you help.  I've not got my N pages per sheet PDF generation complete.
