	FrameRect	Draws a rectangle using the Brush of the canvas to draw the border.
	Free	Destroys an object and frees its associated memory, if necessary.
	FreeInstance	Deallocates memory allocated by a previous call to the System::TObject::NewInstance method.
	GetHashCode	Returns an integer containing the hash code.
	GetInterface	Retrieves a specified interface.
	GetInterfaceEntry	Returns the entry for a specific interface implemented in a class.
	GetInterfaceTable	Returns a pointer to a structure containing all of the interfaces implemented by a given class.
	GetNamePath	Returns the name of the object as it appears in the Object Inspector.
	HandleAllocated	Indicates whether the TCanvas object has acquired a handle to a device context.
	InheritsFrom	Determines the relationship of two object types.
	InitInstance	Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
	InstanceSize	Returns the size in bytes of each instance of the object type.
	LineTo	Draws a line on the canvas from PenPos to the point specified by X and Y, and sets the pen position to (X, Y).
	Lock	Prevents other threads from drawing on the canvas.
	MethodAddress	This is the overview for the MethodAddress method overload.
	MethodName	Returns the name of a class method by address.
	MoveTo	Changes the current drawing position to the point (X,Y).
	NewInstance	Allocates memory for an instance of an object type and returns a pointer to that new instance.
	Pie	Draws a pie-shaped the section of the ellipse bounded by the rectangle (X1, Y1) and (X2, Y2) on the canvas.
	PolyBezier	Draws a set of Bezier curves.
	PolyBezierTo	Draws a set of Bezier curves and updates the value of PenPos.
	Polygon	Draws a series of lines on the canvas connecting the points passed in and closing the shape by drawing a line from the last point to the first point.
	Polyline	Draws a series of lines on the canvas with the current pen, connecting each of the points passed to it in Points.
	Rectangle	This is the overview for the Rectangle method overload.
	Refresh	Deselects the Pen, Brush, and Font from the device context.
	RoundRect	This is the overview for the RoundRect method overload.
	SafeCallException	Handles exceptions in methods declared using the safecall calling convention.
	StretchDraw	Draws the graphic specified by the Graphic parameter in the rectangle specified by the Rect parameter.
	TextExtent	Returns the width and height, in pixels, of a string rendered in the current font.
	TextHeight	Returns the height, in pixels, of a string rendered in the current font.
	TextOut	Writes a string on the canvas, starting at the point (X,Y), and then updates the PenPos to the end of the string.
