In _to_png, it'll be nicer to use driver.fullscreen_window() instead of using driver.maximize_window().

Thank you for providing such a great tool. I was using folium to export some PNG images, and concatenating them into a video. However, the dimension of the exported PNG image is a little bit smaller than common dimensions like 1366x768.
I digged into the source code a bit and discovered that in function _to_png(), driver.maximize_window() was used. If I change this to driver.fullscreen_window(), the dimension of the exported PNG will be the resolution of the (imaginary) screen, like 1366x768.

folium/folium/folium.py

Line 325 in d697154

driver.maximize_window()

This could be a minor improvement.

And btw, does anyone know how to control the (imaginary) screen resolution? Thanks.

I don't have much familiarity with to_png(), but in the meantime, I am using Selenium to create very large screenshots of my maps. Feel free to use the Selenium code near the bottom of this file (starting with "# Finally, the function uses the Selenium library to create a screenshot"): https://github.com/kburchfiel/census_folium_tutorial/blob/master/census_folium_viewer.py

I'm not an expert but fullscreen sounds OK to me. Do you want to send a PR with that change?
