Fix string->number conversion in 3D Tiles inspector

[lilleyse]

Values were being sent as strings rather than numbers, causing the sliders not to work.

@hpinkos could you look at this? I'm not sure if this is the correct thing to do.

Thanks @lilleyse! This looks like the right thing to do

Shouldn't this use Number(value) instead of parsefloat? Number makes sure the number is really a number, parseFloat ignores invalid data (for example "123qwe" will return 123 with parseFloat).

@mramato Yeah, you're right. I didn't think it would make a difference because it will always be a number value coming from the slider. I forgot that you can add invalid characters into the input textbox though.

@lilleyse make sure to add an isNaN check after casting the value to a number. I'm sure we only want to apply it to the tileset if it's a valid number.

Updated.

Is there a way to tell the slider to always return a number? That would also fix this.

[mramato]

There is not, but even if there was you need to handle the case where a user enters a value manually in the text box above the slider.

Thanks @lilleyse.
