View.js entity helper doesnt check for undefined position, scale, and/or rotation

[beewyka819]

The helper() function in View.js currently doesn't check for position, scale, and/or rotation being defined before trying to access their values. This results in MYR crashing if one or more of these fields are undefined.

Suggest adding code that catches this and defaults to 1 instead of hard crashing. Possibly log a warning to the console as well.
