current question icon as used on page
As part of adding tooltips to the Echo preferences screen we added a '?' icon which is hovered over to bring up the tooltip.
Language Engineering has informed me that for inclusion in core we need to have an icon in both SVG and PNG formats and we need both a regular ? and an Arabic ؟.
We are currently using the attached 11x11 px question mark in the development patch(this icon was taken from the UploadWizard extension), you can use this as a base or do something different if you find it appropriate. Also attached is a screenshot of what the page looks like with the current icon in place.
