Subject: mlt_properties.c: make arithmetic processor use floating point instead of integer... 
X-Git-Url: http://research.m1stereo.tv/gitweb?a=commitdiff_plain;h=cee6a62534f2549e343a1b7c489a967577852fc6;p=melted

mlt_properties.c: make arithmetic processor use floating point instead of integer so that '/' is meaningful. I am not totally certain of the consequences of this change because I am not aware of where the feature is used. However, I am using it to specify the aspect ratio of certain things like bitmap graphics that were not designed for square pixels. And being able to specify a fraction allows for accurate detection of equivalent aspect ratios between different sources, particularly compositing.
