Since 3.5 CustomToolbar does not show png icons
Created originally on Bitbucket by Incubant
Until TortoiseHg it worked to have png files in icons directory and it was possible to use them as custom toolbar icon. That does not work in tortoiseHg since version 3.5. Instead of icon the tool name is shown.
And nevertheless i can not find a suitable way to add custom icons to custom toolbar. There are only the default icons shown.
