            Bug ID: 141982
           Summary: [EMF] SetWorldTransform/ModifyWorldTransform support
                    for non-0 m12/m21
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: frob at df.ru

Description:
LO seems to fail to properly apply affine transformation matrices with non-zero
m12/m21 components (rotation or shearing the shapes).

For the simple case with rotated rectangle LO seems to apply transformations to
top-left and bottom-right corners than draw rectangle with an updated bbox.

Steps to Reproduce:
Load attached EMF sample in LO.


Actual Results:
EMF file is not rendered properly

Expected Results:
Proper support of EMF_SETWORLDTRANSFORM and EMF_MODIFYWORLDTRANSFORM


Reproducible: Always


User Profile Reset: No



Additional Info:
More samples are available by request
