SVG image that makes Impress take excessive CPU time.

I have an SVG file I inserted into an Impress slide.  I have a fast Mac with a lot of memory, but moving it around is unusably slow.  Just moving it with the arrow keys, the CPU fans spin up.  This image (attached) is not that complicated.

Can not confirm on Windows 7 sp1, 64-bit en-US with

Build ID: 3a87456aaa6a95c63eea1c1b3201acedf0751bd5

Build ID: 45e2de17089c24a1fa810c8f975a7171ba4cd432
Locale: en_US

However, please recheck with the current release build, or even the current daily of master -- http://dev-builds.libreoffice.org/daily/master/

You might compare behavior of this SVG with the troublesome squirrel SVG attached to bug 88277. Also note that LibreOffice uses two different filters--one for import Open into Draw, and a second for insert as image into any of the components. The two filters differ in structure and can manifest different issues. The "rasterizer.svg" performed about the same with both on Windows.

Still not seeing an issue with Linux 32-bit (Fedora 21 w/LXDE) or Windows 7 sp1 64-bit

The Linux is a VM (VMWare workstation 11, w/4GB Ram on an HDD), VM CPU use ~35-40% when moving the multi-element SVG.  On the 64-bitWindows system, 12 GB Ram i7--920 @2.7GHz, 32-bit LO peaked ~24% CPU during movement.  64-bit build LO ~23% CPU during movement.

Duping this to bug 83426

Complex SVGs in Impress degrade presentation mode--but they also disrupt slide editing as in this extreme example.
