Avoid color copies for rendering Draw calls in
GUIRenderer::UpdateDrawCallCache, CButton::Draw, CChart::DrawAxes,
CDropDown::Draw, CList::DrawList, COList::DrawList, refs #1984,
8f4f8e240f, 3028551b91, a905fbbc98.
Avoid color copies during XML loading in CGUI::Xeromyces_ReadImage,
CGUI::Xeromyces_ReadEffects, COList::HandleAdditionalChildren.
Add CGUI::HasPreDefinedColor and mark m_PreDefinedColors,
CGUI::GetPreDefinedColor, IGUIButtonBehavior::ChooseColor() as const for
consistency with the other "databases", refs 3028551b91.
Mark CGUIColor as NONCOPYABLE to add compiler errors if there is an
unexplicit copy, refs 3028551b91.
Explicit ugly copy in CGUI::Xeromyces_ReadColor and
CGUIColor::ParseString.
Deregister copying <CGUIColor>GetSetting functions, refs 8f4f8e240f.
Uses the const ref GetSetting from 3dfa23cd25.
This was SVN commit r22694.
Makes GUI text construction 30x faster for empty strings, otherwise less
than 1% faster.
Split the constructor into smaller helper functions to reduce nesting
and improve readability.
Change m_GeneratedTexts from pointer to reference, so that one doesn't
have to keep track to delete it correctly in several places, without
having to resort to copy or move assignments but constructing in place.
Mark CGUIText as NONCOPYABLE and MOVABLE which is already implicitly the
case due to the CGUISpriteInstance members, refs 0a7d0ecdde/D2133,
D2163/3028551b91.
