Report Page Tooltip Support

[Daniel Marsh-Patrick]

As this has been introduced, we should see if we can add it in.

Note that in order to make this work, we will need to migrate the tooltip object into visualTooltip (which is what Power BI uses for the report page tooltip handling).

There is some discussion in this community thread about what we need to do to make this work. In order to support the orginal versions of the visual we need to retain the old object and settings.

[Daniel Marsh-Patrick]

Due to recent changes in the Service & Desktop, a bunch of new tooltip customisation options have become available as standard. Through further investigations, on the above point, we don't yet have an answer on how to migrate the existing tooltip configuration into the existing menu; as we cannot access these objects in the custom visuals framework, I think that it's not a particularly good idea that we try to merge these as a result. Current thinking is that we will rename the exsiting menu to handle default tooltip-specific behaviour and yield control of the tooltip to the legacy tooltip menu.

• Added report page tooltip support, and enabled standard tooltip menu (to suppor tMarch 2019 changes in Power BI for tooltip formatting)
• Yielded control of tooltips to the visual host, as we can't get access to the values from standard menus
• Renamed the Tooltip menu, as while we can migrate the objects into the standard menu, we can't manage them based on the standar objects, so it makes more sense to just name our custom menu more explicitly and leave the standard Tooltip menu as-is
