Support for DIN A2, A1 and A0 formats in the polybios plugin

[domenikov]

I would like to ask whether other print formats could be included for the 'size' parameter of the 'page:SetSize' command. Personally, I would be interested in the DIN A2, A1 and A0 formats, but other formats, e.g. of the B series, could probably also be of interest.

New formats could be defined by adding new constants defining them (e.g. for A2, the constant #HPDF_PAGE_SIZE_A2 could be introduced).

including CUSTOM, no reason for constants.. just a free size variable and you set the size

The predefined page formats are managed by libharu so this feature request should be submitted to the libharu maintainers. Then Polybios could support them as well.
