Apple'i arendatav veebimootor WebKit, mida kasutatakse sellistes brauserites nagu Safari ja Epiphany (GNOME Web), l\u00e4heb \u00fcle Skia teegile, mida kasutatakse 2D-graafika renderdamiseks Google Chrome'is, ChromeOS-is, Androidis ja Flutteris ning mis toetab GPU-d kasutavat renderdamist. Portimise teostas firma Igalia osana WebKitGTK j\u00f5udluse optimeerimise algatusest GNOME'i jaoks. Migratsiooni p\u00f5hjuseks mainitakse CPU kasutamisel 2D renderdamise j\u00f5udluse optimeerimise piiride saavutamist ning vajadust aktiivselt kaasata GPU edasise j\u00f5udluse parandamiseks. <\/p>\n

Cairo teegi lisamisest, mis t\u00f6\u00f6tas WebKitis, 2D-renderdamiseks GPU abil ei saanud tingitud selle teegi arhitektuurilistest omadustest. Omandava renderdamise teegi kirjutamise projekt loobuti t\u00e4nu raskustele j\u00f5uda tasakaalu vahel j\u00f5udluse ja kvaliteedi. L\u00f5puks p\u00f6\u00f6rdusid Igalia arendajad tagasi Skia teegi kasutamise idee juurde, mis oli optimaalne lahendus, kuid algselt k\u00f5rvale heidetud, kuna puudus stabiilne API, esines probleeme selle kasutamisel v\u00e4lise s\u00f5ltuvusena ja on vajalik kolmanda osapoole mooduli hooldamine WebKitis. <\/p>\n

WebKiti \u00fcleminek Skia teegile sai t\u00f5uke sellest, et asendamisega seotud puudused \u00fcletasid eelised, mis v\u00e4ljendusid mitte ainult renderdamise j\u00f5udluse suurenemises, vaid ka koodibaasi lihtsustamises ja v\u00f5imaluste avardamises uue funktsionaalsuse arendamiseks. Mis puutub j\u00f5udlusesse, siis esialgne WebKiti port Skiale n\u00e4itas MotionMarki testide l\u00e4bimisel kahekordset kiiruset\u00f5usu v\u00f5rreldes vana CPU-p\u00f5hise koodiga. <\/p>\n

2024. aasta veebruariks oli Skiale \u00fclemineku saanud WebKiti haru valmis edastamiseks WebKiti koodibaasi p\u00f5hijuurde. P\u00e4rast arutelusid Google'i, Sony, Apple'i ja Red Hati arendajatega tehti otsus WebKiti \u00fcleviimiseks Cairo raamatukogult Skiale ning praegu on Skia toe kood juba p\u00f5hiharusse aktsepteeritud.
