Styling plotnine

[JanPalasek]

Hello, I would like to create a style for plotnine. I found out how to create a theme and successfully did it, however I still struggle with a few problems.

• How can I set a default color cycler for continuous and nominal? I want to use LinearSegmentedColormap directly instead of providing its name.
• How can I set colormap for continuous and categorial variable in the plot? I would liek to use again classes directly (LinearSegmentedColormap class) instead of specifying colormap. Alternatively, I would like to use name defined by me, e.g. my cmap has name color_red_blue.
• How can I change title position? I would like to use matplotlib axes.titlelocation: left from rc config.
