- Expanded FDeprecateSlateVector2D to provide structs for parameters, return types and member variables that use FVector2f, while still allowing conversion to/from FVector2d with optional per-module deprecation mechanisms. - Many of the high-traffic SlateCore types like FSlateBrush, FGeometry and FSlateLayoutTransform have been converted to use these deprecation mechanisms. - Some legacy FGeometry::ToPaintGeometry and MakeChild overloads have been explicitly deprecated since they cause ambiguous overloads with FSlateLayoutTransform if it were to support implicit construction. - Deprecated ULocalPlayer::GetPixelBoundingBox and GetPixelPoint to prefer FVector2f for OptionalAllotedSize parameter since this parameter is expected to come from FGeometry - Exposed FVector2f members to blueprints #jira none #rb Andy.Davidson, Dave.Jones, Vincent.Gauthier, Patrick.Boutot #preflight 63bc6fd068068a8bd6027c9f [CL 23631073 by Andrew Rodham in ue5-main branch]
