Resolves: tdf#87083 images in help html stuck at default placeholder size

regression from the SwapIn work.

The graphic size during SetGrfFlySize appears to assume its the pre-swapped in
size, i.e. the old 0 by 0 "size is not set" for an html image used to be the
value used here. So get that value (and update it if necessary) before updating
the image data and pass that to SetGrfFlySize

Without the swap-in in the html filter the data gets swapped in during the
initial draw of the image which is too late to update the image size, so
restore the equivalent of that swap-in via GetTwipSize

    Make SwGrfNode swapping methods private

    Change the filter test accordingly.
