Inconsistencies in certain icons over themes

[PanderMusubi]

Certain icons are not centered identically between the filled theme and other themes or other inconsistencies need to be fixed. I have found the following 18 inconsistencies:

In filled theme more to the left:

• action / accesible_forward
• action / label_important
• communication / phonelink_setup has different
• device / airplanemode_active
• device / airplanemode_inactive

In filled theme more to the top:

• action / event
• image / wb_incandescent
• image / wb_iridescent

In filled theme more to top and right:

• action / view_list
• device / screen_lock_rotation

In filled theme more to the top:

• action / visibility
• action / visibility_off

In filled theme more to the left:

• maps / local_airport (flight is correct)
• navigation / arrow_back_ios (arrow_forward_ios is correct)

Also the outlined theme is unneeded small than the filled theme for:

• alert / notification_important (see add_alert for correct same size version)

Other issues with icons:

• av / slow_motion_video (the play triangle is damaged in filled theme)
• social / emoji_food_beverage (line under the cup is missing small part on the left, see other themes where it is okay)
• social / group_add (the part of the two persons is varying in height over all themes where other usage of these two is not doing that in other icons, the + part is okay)

All these differences can be found by switching back and forth of the filled and outlined style in https://material.io/resources/icons/ (Please, also check other themes but most differences are between filled and outlined.) Best is to double check all, is some work but will increase quality of the icons set.

Thanks for the extensive report! These should be address. I'll mark them as icon bugs.

I think these are all addressed in the new Material Symbols versions, but may still be issues for the old Material Icons.
