Unfortunately the StrokeComponent class 00119 was written making extensive use of friend classes calling static functions, this did not lend 00120 itself particularly well to inheritance so what we currently have is a load of functions in the 00121 LineComponent class which are ripped from StrokeComponent, however the Brush component is the only 00122 one that makes use of them as all the stroke code is in place with these static functions. 00123 If I have time to rework the stroke component code then I will try to sort this out. */ 00124 00125 /******************************************************************************************** 00126 00127 > typedef UINT32 LineHandle;
