G2D.Color is defined as BGRA, but most of the implementation assumes RGBA
The only case, which seems to use BGRA is org.simantics.diagram.connection.ConnectionVisuals
. Even org.simantics.diagram.G2DUtils
, which is used by many color handling components, assumes RGBA.
Easiest wasy to move forward is to change G2D.Color
specification to RGBA and change ConnectionVisuals
accordingly.
