kOfxParamPropInteractMinimumSize

[PierreJasmin]

define kOfxParamPropInteractMinimumSize "OfxParamPropInteractMinimumSize"

If we change type for:

define kOfxParamPropInteractSize "OfxParamPropInteractSize"

Do we need to rename to something like: #define kOfxParamPropInteractSizeD "OfxParamPropInteractSizeD"

to be safe and move kOfxParamPropInteractSize to ofxOld
