I agree and do address that in a follow-up patch in the LBSE downstream branch, however this only aims to remove the code duplication, postponing cleanups to later. Ok with you? 1848665 5 zimmermann 2022-03-07 03:07:31 -0800 (In reply to Darin Adler from comment #2) > Comment on attachment 453834 [details] > Patch, v1 > > View in context: > https://bugs.webkit.org/attachment.cgi?id=453834&action=review > > I wonder at what point these function implementations get long enough that > we want to move them out of the class definition.

Good point! In LBSE I'll have to add another condition to hasTransform(): checking for hasSVGTransform(). Prior to this patch I had to fix two call sites: the one in RenderObject.h and in RenderGeometryMap.cpp -- I want to avoid having to touch more than one place to add such a condition. I'll amend the ChangeLog a bit to include that information. Thanks for the review, and sorry for the late reply: I was on sick leave.... More patches will follow today, cleaning up transform-box handling, individual bugs in perspective-origin, transform-box + compositing, etc. 1848670 6 zimmermann 2022-03-07 03:19:04 -0800 Committed
