Re-sync after coa-ace3 3ec2009 added two CoA-compat patches:
- AceGUI-3.0/widgets/AceGUIContainer-BlizOptionsGroup.lua: parent
falls back to UIParent when InterfaceOptionsFramePanelContainer is nil
- AceConfig-3.0/AceConfigDialog-3.0: Settings.* block guarded with
fallback to InterfaceOptions_AddCategory on WotLK-era clients
Without these, every addon registering a Blizzard Interface Options
panel via AceConfigDialog errors on load on the CoA client.
Re-sync after coa-ace3 d422ad3 which converted 42 numeric FileDataIDs in
Set*Texture() calls back to string paths. Upstream Ace3 uses FDIDs which
silently fail on WoW 3.3.5 / CoA, rendering color swatches, checkboxes
and window chrome as solid-red placeholders.
