This property determines whether ActiveX is enabled.
By default ActiveX is disabled when rendering HTML
This is done for good security reasons and we strongly recommend
that you do not change this setting.
However if you are sure that your source documents do not pose a
security risk you can enable ActiveX using this setting.

with ABCpdf. In particular some rely on being able to draw direct
to screen which stops ABCpdf being able to use them.
