	@title:
		painter class
	@type:
		class
	@short:
		This class provide a painter to paint line and shapes.
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		With this class you can draw many graphics objects from simple lines to complex shapes like pies and chords.[br]
		It can also draw aligned text and pixmaps. Normally, it draws in a "natural" coordinate system, but it can also do view and world transformation.[br]
		The class need to be implemented into a [classfnc]$paintEvent[/classfnc]();
		@functions:
		!fn: $drawLine(<x1:integer>,<y1_integer>,<x2:integer>,<y2:integer>)
		Draws a line from (x1, y1) to (x2, y2) and sets the current pen position to (x2, y2).
		!fn: $begin(<paint_device:object>)
		Begins painting the paint device <paint_device>: the parameter MUST be a widget or a pixmap.[br]
		Warning: A paint device can only be painted by one painter at a time.
		!fn: $end()
		Ends painting. Any resources used while painting are released.
		!fn: $setPen(<rgb or hsv array value or [<red>,<green>,<blue>][<hue>,<saturation>,<value>],[system color:RGB or HSV)
		The pen defines the lines or text, color. You can set it with Red,Green,Blue, or H,S,V value[br]
		All parameters are in integer form.
		The HSV system, like RGB, has three components:[br]
		* H, for hue, is either 0-359 if the color is chromatic (not gray), or meaningless if it is gray.[br]
		  It represents degrees on the color wheel familiar to most people. Red is 0 (degrees), green is 120 and blue is 240.[br]
		* S, for saturation, is 0-255, and the bigger it is, the stronger the color is. Grayish colors have saturation near 0; very strong colors have saturation near 255.[br]
		* V, for value, is 0-255 and represents lightness or brightness of the color. 0 is black; 255 is as far from black as possible.[br]
		Examples: RED is H=0, S=255, V=255.[br]
		Light RED could have H about 0, S about 50-100, and S=255.
		ES: $setPen(00,00,00) for black;[br]
		Default color mode is RGB;
		!fn: $setBrush(<rgb or hsv array value or [<red>,<green>,<blue>][<hue>,<saturation>,<value>],[system color:RGB or HSV)
		Sets the painter's brush to have the specified color.[br]
		Example:[br]
		class (wdg,widget)[br]
		{[br]
			paintevent()[br]
			{[br]
				%b=$new(painter)[br]
				%b->$setBackgroundMode(Opaque)[br]
				%b->$setBrush(0,250,250)[br]
				%b->$begin($$)[br]
				%b->$drawEllipse(50,50,100,50)[br]
			}[br]
		}[br]
		%aa=$new(wdg)[br]
		%aa->$show()[br]
		!fn: $drawRect(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>)
		Draws a rectangle with upper left corner at (x, y) and with width w and height h.
		!fn: $drawWinFocusRect(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>)
		Draws a Windows focus rectangle with upper left corner at (x, y) and with width w and height h.[br]
		This function draws nothing if the coordinate system has been rotated or sheared.
		!fn: $drawRoundRect(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>,<xCor:integer>,<yCor:integer>)
		Draws a rectangle with rounded corners at (x, y), with width w and height h.[rb]
		The xCor and yCor arguments specify how rounded the corners should be (range is 0->99).
		!fn: $drawPie(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>,<angle:integer>,<alen:integer>)
		Draws a pie defined by the rectangle (x, y, w, h), the start angle a and the arc length alen.[br]
		The angles <angle> and <alen> are 1/16th of a degree, i.e. a full circle equals 5760 (16*360).
		!fn: $drawArc(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>,<angle:integer>,<alen:integer>)
		Draws an arc defined by the rectangle (x, y, w, h), the start angle a and the arc length alen.[br]
		The angles <angle> and <alen> are 1/16th of a degree, i.e. a full circle equals 5760 (16*360).
		!fn: $drawPoint(<x:integer>,<y:integer>)
		Draws a point at x and y coordinates.
		!fn: $drawEllipse(<x:integer>,<y:integer>,<sizew:unsigned integer>,<sizeh:unsigned integer>)
		Draws an ellipse with center at (x + w/2, y + h/2) and size (w, h).
		!fn: $drawChord(<x:integer>,<y:integer>,<w:unsigned integer>,<h:unsigned integer>,<angle:integer>,<alen:integer>)
		Draws a chord defined by the rectangle (x, y, w, h), the start angle a and the arc length alen.[br]
		The angles <angle> and <alen> are 1/16th of a degree, i.e. a full circle equals 5760 (16*360).
		!fn: $drawText(<x:integer>,<y:integer>,<text:string>,<nr chars:integer>,<dir:enum>)
		Draws the given <text> at position <x>, <y>.[br]
		If <len> is -1 (the default) all the text is drawn, otherwise the first <len> characters are drawn.
		The text's direction is given by <dir>, valid flag are:[br]
		[pre]
		Auto [br]
		RTL (right to left) [br]
		LTR (left to right) [br]
		[/pre]
		!fn: $drawPixmap(<x:integer>,<y:integer>,<pixmap:hobject>,<sx:integer>,<sy:integer>,<ex:integer>,<ey:integer>)
		Draws a pixmap at x,y coordinates[br]
		!fn: $setFont(<size:unsigned integer>,<family:string>,<style:enum>)[br]
		Set the font's size, family and stile, valid flag for style are:[br]
		[pre]
		italic     [br]
		bold     [br]
		underline      [br]
		overline    [br]
		strikeout  [br]
		fixedpitch  [br]
		[/pre]
		!fn: $setFontSize(<size:unsigned integer>)[br]
		Set the current painter font's size.[br]
		!fn: <integer>$fontAscent()
		Return the distance from the baseline to the highest position characters extend to.
		!fn: <integer>$fontDescent()
		Return the distance from the baseline to the lowest point characters extend to.
		!fn: <integer>$fontMetricsWidth(<text:string>)
		Returns the font metrics width for the painter's current font.
		!fn: <integer>$fontMetricsHeight()
		Returns the font metrics height for the painter's current font.
		!fn: $rotate(<angle:real>)
		Rotates the coordinate system a degrees counterclockwise.
		!fn: $translate(<dx:real>,<dy:real>)
		Translates the coordinate system by <dx>, <dy>.
		!fn: $shear(<dh:real>,<dv:real>)
		Shears the coordinate system by <dh>, <dv>.
		!fn: $scale(<dh:real>,<dw:real>)
		Scales the coordinate system by <dh>, <dv>.
		!fn: $setBackgroundMode(<bgMode:enum>)
		Sets the background mode of the painter to <bgMode>: valid values are:[br]
		- Transparent	(that is the default value);[br]
		- Opaque.[br]
