           Summary: DrawImage(Image* image, Point destPoints[], Rectangle
                    srcRect, GraphicsUnit srcUnit) not allowing rotating
                    of images

Sample program that demonstrates DrawImage

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.5

DrawImage should allow rotating of images, by specifying certain destPoints.

"The destPoints parameter specifies three points of a parallelogram. The three
Point structures represent the upper-left, upper-right, and lower-left corners
of the parallelogram. The fourth point is extrapolated from the first three to
form a parallelogram." - from MSDN


so something like this:

Point[] p = new Point[3];
p[0] = new Point(500, 0);
p[1] = new Point(500,500);
p[2] = new Point(0, 0);

e.Graphics.DrawImage(bitmap, p, new Rectangle(0, 0, 500, 500),
GraphicsUnit.Pixel);

should draw a rotated image




Reproducible: Always

Steps to Reproduce:
1. Compile and Run test program

Actual Results:  
A single, 10 pixel wide, vertical line is drawn

Expected Results:  
a 10 pixel wide, vertical line is drawn and 
a 10 pixel high horizontal line is drawn.
