Sample slide (PPTX)

1. Open sample document in Impress and PowerPoint
2. Observe how the colors on the left half of the slide appear much
   stronger/darker in Impress.

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 47ca3f1f762352b488d58b3bf23d5776576f1cca
CPU threads: 8; OS: Linux 6.4; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US

and back to 7.0.  6.4 has the color right, alas the shape wrong.


If I had to guess I'd say this is a regression introduced (or incomplete
implementation) related to bug #140714

  "FILEOPEN PPTX: image styles that clip images into curvy shapes 
  missing (and images shown rectangular)"
