Flat design in ios 7 is a necessity?

Skeumorphysm in prior ios iterations was provided though actual bitmap images, correct?

New IOS 7 employs flat design (vector graphics?) that will be a lot easier to scale for different resolutions, allowing for larger screens. No need for previously employed workaround of increasing pixel count by factor of 4.

I could be wrong, but I highly doubt they're vector graphics. Taking an educated guess I still think they're bitmap images. Again just my educated guess.

Even if ios 7 still uses bitmap images, they are a lot easier to scale
