So how would functions that take TColor parameters work? For example,
drawing a gradient with increasing Alpha value, say via a
TCanvas.GradientFill() call. In the case of GradientFill() it has a
Start/Stop TColor parameter. Also other functions like
DrawGradientWindow() etc. So for each such cases, new overloaded
versions will be implemented, replacing TColor with TFPColor?
