This patch moves some stuff that needs to be done for every item up to the front of the function, then checks to see if the item is being added in an area that's already opaque and visible. If so (and assuming the color-layer optimization has already been disabled), none of the rest of the method would do anything so we can exit early. In particular we avoid calling IsUniform and GetOpaqueRegion on the item, and we also avoid some expensive region manipulation. |

An explanation of the Mozilla Source Code Directory Structure and links to project pages with documentation can be found at: https://developer.mozilla.org/en/Mozilla_Source_Code_Directory_Structure For information on how to build Mozilla from the source code, see: http://developer.mozilla.org/en/docs/Build_Documentation To have your bug fix / feature added to Mozilla, you should create a patch and submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at: http://developer.mozilla.org/en/docs/Creating_a_patch http://developer.mozilla.org/en/docs/Getting_your_patch_in_the_tree If you have a question about developing Mozilla, and can't find the solution on http://developer.mozilla.org, you can try asking your question in a mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups are accessible on Google Groups, or news.mozilla.org with a NNTP reader.] You can download nightly development builds from the Mozilla FTP server. Keep in mind that nightly builds, which are used by Mozilla developers for testing, may be buggy. Firefox nightlies, for example, can be found at: ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/ - or - http://nightly.mozilla.org/
