Audit API around LTR experience

[bitspittle]

Compose, being a savvy API, specifies things as start to end, while HTML / CSS specifies left to right. Since I'm smashing both APIs together, this can end up with a confusing experience where you create rows and columns with start / end parameters while creating elements within the layouts using modifiers that take left/right/top/bottom values.

Is there anything we can do about this? It would be nice if I could create alternate modifiers that take "start/end" instead of "left/right" parameters.

I need to dig a bit into how LTR works on the web.
