height 4090 ?

[simonmcnair]

This implies that the svg should be taller than it is wider ? Is this correct ? Just curious Should the width and height be fixed or are they arbitrary ?

Cheers

Width and height may vary depending on the options used.
Most of the time the canvas is taller than it is wide (this is because the different views are stacked vertically). But if option packed is used then views from the same activity are grouped on the same row (horizontally), making the canvas wider that it usually is.
Wrt height, this is a best guess and the value is often bigger that necessary (see #286).
