Python dependency

[Simon McNair]

Hi,

I found that renderPM failed until I installed  libcairo2-dev.  I found the link to fix it here:

https://stackoverflow.com/questions/70508775/error-could-not-build-wheels-for-pycairo-which-is-required-to-install-pyprojec

should libcairo2-dev be required for this to be compiled and if so, why is it not in the requirements please ?

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPM

drawing = svg2rlg('input/ice.svg')
renderPM.drawToFile(drawing, 'output/ice.png', fmt='PNG')

Cheers

Simon
