Remarks of some OpenGL functions

1. glrect

void glRectd	(	GLdouble x1 , GLdouble y1 , GLdouble x2 , GLdouble y2 );
void glRectf	(	GLfloat x1 , GLfloat y1 , GLfloat x2 , GLfloat y2 );
void glRecti	(	GLint x1 , GLint y1 , GLint x2 , GLint y2 );
void glRects	(	GLshort x1 , GLshort y1 , GLshort x2 , GLshort y2 );

X1, Y1, is the lower left vertex, X2, Y2 is the upper right vertex.
