Please rename to match our other icon names (lowercase).

Also a few requests:

• I think this should be corner_helicopter_2x2x2 or corner_helicopter_222
• The rounding of corners is a bit inconsistent. We're also not 100% consistent across all our icons, but I think they should be sharp rather than beveled/rounded unless this causes rending issues.
• I think this is quite pleasing at large scale, but the corners get very narrow at small scales. Is it possible to adjust the cuts so the stickers are closer to equal size?

@hopz123, looks like the tests are failing with this new icon. Please fix and we can merge this.

I still have a few concerns about this icon. In addition to the points above, it's also much larger than necessary — almost twice as large as any other event icon.
