Description: The basics of this program is to develop a simple 2D paint program, similar in function in many respects to MS Paint. provide the user access to the following functions:
Point in this mode, each left mouse down should create a point on the screen
Scribble in this mode, user should be able to draw “freehand” lines with left mouse down
Line in this mode, the user can draw a line between two points selected with two successive clicks of the left mouse button

Description: BspLines曲线生成
Step1：建立控制点数组；
Step2：设定插值步长、曲线Si的控制点、参数t的取值区间为(0,1)；
Step3：用OPENGL画出各控制点及其连线；
Step4：进行插值计算：计算出的若为第一个插值点定位到画图窗口否则画曲线到该点。
-BspLines curve generation Step1: establish control points group Step2: Set interpolation step, the curve control points Si, the parameter values t interval (0,1) Step3: Draw the control points with OPENGL and its connection Step4: interpolation calculation: if the calculated interpolation point positioning for the first one to paint the window or painting curve to that point.
