Access to Icons/Images stored in Ignition internal DB

I am working on developing new modules to extend Ignition functionality, and want to insert entries in to the Ignition Designer Project Browser. To make the UI for my deliverables more consistent with core product, I would like to reuse some of the icons used by core product within the Project Browser tree (such as the New Folder icon). Can I do this, and how?

I know I can create and use my own Icons, but would prefer to keep things consistent with product.

Upon doing a fresh install of Ignition, there will be a folder in the install directory with all of the builtin images as PNG files. I believe these get compiled into the internal DB and disappear once you’ve launched a designer so go grab the folder with the images in it before launching the designer for the first time. Make a copy of the folder and put it somewhere else for later use.
