Hello, I am trying to modify someone else's litex code but I don't fully understand how it works yet.

I'm specifically looking at the video driver… it's doing a thing where it's given a framebuffer pointer in RAM, and it reads it as a 266-pixel-wide matrix of pixels and scans them left-to-right then top-to-bottom.
I'd like to change it so the distance between "rows" (when it reads from RAM) is some number of bytes other than 266*pixelsize, but it is happening inside LiteX code. We ( https://github.com/agg23/openfpga-litex/blob/master/litex/analogue_pocket.py#L128 ) call a LiteX function `add_video_framebuffer` ( https://github.com/enjoy-digital/litex/blob/master/litex/soc/integration/soc.py#L2353 ). I don't find documentation for either this or VideoGenericPHY, but maybe I just don't know where to look.

Is there documentation for `add_video_framebuffer` or anything close to it that might help me understand how to configure or alter it?
