Regression from commit 02c4350820 (sw keep
aspect ratio: add filter for this setting, 2021-06-07), once UI units
are set to poins (instead of cms), the image dialog for the bugdoc was
showing 5% width instead of 48%.
48% is roughtly correct, visually the image is taking half of the body
frame width. Previously the bad rel size didn't happen because we didn't
save the "keep aspect ratio" to documents, so it was off by the time the
dialog was initialized.
Fix the problem by introducing a new flag, so we can differentiate
between the user changine the width or height vs the dialog being
initialized. RelSizeClickHdl() is meant to adjust the other axis in the
user case, and this is not wanted in the init case.
A higher level fix would be to make sure once aspect ratio is kept,
that ratio is stored in documents explicitly, so we can say 50% wide
with e.g. 4:3 ratio, that would avoid all this trouble by even looking
at the calculated sizes when we want to work with percents. This storing
of the aspect ratio is not done here.
