Subject: allow a number of enter events to be ignored. Don't just skip any enter/leave events... 
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=6c4126ec617ccb0dd4e6bf0e3aecaa2181172c66;p=chaz%2Fopenbox

allow a number of enter events to be ignored. Don't just skip any enter/leave events as these are used for highlighting hover buttons and ignoring these makes the hover state out of sync sometimes
