[Lazarus] ColotToRGB in GTK apps

[Valdas Jankūnas]

Hello,

   I found solution: in unit GtkProc is procedure UpdateSysColorMap that 
updates SysColorMap array (from where ColorToRGB gets RGB values of 
system colors), but functionality of this procedure is disabled 
("NewSysColors" is not defined). So i writed own procedure that based on 
code of mentioned procedure. Now this procedure I call in OnCreate and 
then ColorToRGB returns correct values.
