Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/3815

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/15/3815/1

Fix fdo#40421 Take current clip into account for shape bounds.

Seems with the extensive drawinglayer rework, we now get bitmap
fills rendered via clip polygon and subsequent bitmap tiles. To
get the true bound rect of the current metaaction, clip it against
outdev's clip region bounds (as some reasonably cheap best-effort
approximation).
