A patch from Deepak Dixit for "Scale logo to fit content area in PDF which are based on simple decorator" https://issues.apache.org/jira/browse/OFBIZ-5006

Now logo image will be display over order pdf. Default value set in fop decorator not working properly, global set to true, Also added check in company header groovy, if logoImageUrl found in groovy then only set to context else default will be used.

Also set the logo width in company header fo.ftl as if logo image is large then it will throw warning related to content overflow on console.
