Font size unit issue

### Expected Behaviour
The documentation indicates that the default font size unit for text layers is in point: fontSize | float | in points. So, i'm expecting to retreive the value in points

### Actual Behaviour
But, from what I see in my tests, the values returned are in pixels not in points.

### Reproduce Scenario (including but not limited to)
Retreive any JSON manifest from the API and have a look at the layer text characterStyle fontSize

Is there a way to know the current unit? and/or to specify it when calling the API to get the manifest?

Start with the documentation describing the text layer's characterStyle.fontSize and compare it with the value returned in a JSON manifest from the API. Verify whether the returned value is pixels or points and whether the API exposes or accepts a unit setting. Done means the documentation accurately states the unit and explains how to determine or specify it, if supported.
