// 0,16777215,BI,0,1,0,15

// background color (RGB): 16777215 ($FFFFFF)
// font style: BI (bold italic), possible flags: B(old), I(talic), U(nderline)

// foreground index: 0 (foreground index (Pal16), corresponds to foreground RGB color)
// background index: 15 (background index (Pal16), corresponds to background RGB color)
// Delphi 4.0 & 5.0:
// In the registry branch HKCU\Software\Borland\Delphi\4.0\Editor\Highlight.

// Foreground Color: foreground index (Pal16), 0..15 (dword)

// Bold: fsBold yes/no, 0/True (string)
