New commits: commit b69b6eff232ac7e4897a28cc3422aa61171f4329 Author: Michael Meeks <michael.me...@suse.com> Date: Wed Dec 12 11:29:37 2012 +0000 fdo#58029 - substantially accelerate re-rendering of complex forms Some writer VCL Windows appear to have thousands of children. Remove an N^2 in handling them, and let VCL do the job instead. i#103611 continues to stay fixed for simpler code.
