MacOSX dock icon too small

The dock icon that is shipped with the dmg for MacOSX of XEclipse is very small within a big rectangle. This is inappropriate at least to let users recognize the application.

Find attached an icns file that solves this. I couldn't find the logo in original or vector form so the quality could be a bit enhanced... but that's at least one big step.
Also, there's no transparency in there.
