Minimize children vector capacity changes in PlatformCALayerRemote::recursiveBuildTransaction()
https://bugs.webkit.org/show_bug.cgi?id=147446
Reviewed by Simon Fraser.
Minimize children vector capacity changes in PlatformCALayerRemote::recursiveBuildTransaction()
by leveraging the fact that we know in advance how many layer IDs are going to be added. We
now set the Vector size from the start, instead of clearing it and then growing the vector
capacity when appending the layer IDs one by one.
* WebProcess/WebPage/mac/PlatformCALayerRemote.cpp:
(WebKit::PlatformCALayerRemote::recursiveBuildTransaction):
