Revert "fdo#74336 need to transform dash length / dot length / distance"

This reverts commit 17ca93a6e592d3109e47c756fcfe8ac975acae5f.
fdo#74336 limit the size of the non-placeable WMF image

For a non-placable WMF image the size is unknown and needs to be
calculated by using a bounding box over all elements. Sometimes
this results in a very big image which is not drawn correctly
when using dashes and dots. This change normalizes the size to
reasonable values.
