RFE: improve consistency between simulator fonts and device fonts

[ThomasH99]

I've noticed that the look of the UI, and notably the size and weight of fonts, can be very different between the simulator and the app running on the device.

Since device test cycle (adjust fonts, recompile, install, test) is slow, it would be a huge benefit to have the fonts in the simulator be as identical to the device fonts as possible.

I suppose that there are copyright issues that prevent including in CN1 the iPhone native fonts.
About the size, I suppose that it depends on the accuracy of the screen density reported by the device.

I workarounded the issue of the size of fonts writing methods that adjust all the font sizes (specified in mm) in my UIIDs according to the screen size recognized by CN1 (they also adjust margins and paddings). For example, if I make an UI assuming that the screen length is 70mm, than my method (in the init()) calculates the percentage variation of the font sizes to fit in a screen width that is different from 70mm. Of course it makes sense only for smartphones in a locked orientation, but it helped me to get more correct font sizes even in smartphones that reports their screen density wrongly to CN1 (like a lot of Huawei models, in which the fonts by default are bigger than the given mm).

As requested by Shai recently, I bump up a few old RFEs. This is a small thing but would be really nice to have exactly the same fonts when simulating as on real device (especially on iOS when using the native fonts). If there are copyright issues, maybe document if there is a work-around allowing individual developers to use the available native fonts for their own use?
