Queryable transformation stack

Increasing access

This would make it easier to get previous and current transformations for things like layer transformations (previously only possible with undocumented methods) on top of one another, which would be great for things like editing programs that could use multiple transformations (e.g. 2d models, 3d art), and it would also help with debugging.

Feature request details

Create a function that returns a list containing transformation data (could be a list containing the data in any format it shouldn't really make a difference) for each transformation in order (preferrably so that the first/base transformation is at index 0).

No file, test, or entry point is named. Start by locating the WebGL/core rendering transformation handling and the undocumented methods referenced in the issue; the work is complete when an agreed function exposes each transformation in order, with the base transformation first.
