Which application can read custom shapes?

[Regina Henschel <rb.henschel@t-online.de>]

Hi all,

in section "19.171 draw:formula" in ODF1.2 part 1 the angle for sin, cos 
and tan is specified to be in degrees. In Apache OpenOffice it is 
implemented in radians. Now I want to investigate how other application 
have implement this.

I have already tried "PowerPoint 2013 Preview", "LibreOffice", and 
"Calligra Stage". All of them implement 'radians'.

Do you know other programs, which are able to read a draw:custom-shape 
element, contained in a .odg or .odp file, for example?

Kind regards
Regina
