== ((Control drawing)) functions ==

=== Starting/stopping ===
You can draw in a number of different modes.
In the default mode, you draw directly to the control on screen.
((startSetPixel)) - Start drawing on an ((OWNERDRAW))
((endSetPixel)) - Stop drawing
The buffer mode lets you draw off-screen without a control. Use this mode if you want to use these functions to draw to something other than a control and use ((getPixel)) to transfer information between the buffer and your target.
((startSetPixelBuffer))- Start drawing in buffered mode
((endSetPixelBuffer)) - Stop drawing buffered mode. This destroys the buffer.
In SuperSampling mode, you draw at a scaled up resolution off-screen, after ending the result is scaled down and smoothed.
((startSetPixelSS)) - Start drawing in SuperSampling mode
((endSetPixelSS)) - Stop drawing SuperSampling mode

=== Meta ===
((getSetPixelHeight)) - Returns the height of the control canvas or buffer in pixels. Only works between a startSetPixel* and endSetPixel* pair.
((getSetPixelWidth)) - Returns the width of the control canvas or buffer in pixels. Only works between a startSetPixel* and endSetPixel* pair.

=== Pixels ===
((getPixel)) - Read single pixel
((setPixel)) - Set single pixel

=== Text ===
((setFont)) - lets you choose the font name, its size, angle, boldness, and italics 
((setText)) - lets you draw a certain text with the chosen font, color and alignment
((setTextv)) - Identical to ((setText)) but with support for formatted text.

=== Bitmaps ===
((setBitmap)) - Draw a specified bitmap on the current ownerdraw/buffer canvas at the specified coordinates.
((setBitmapTransparent)) - Draw a bitmap on the current ownerdraw/buffer canvas with a transparent color.
((setBitmapStretch)) - Draw a stretched or shrunk bitmap on the current ownerdraw/buffer canvas.
((setBitmapTile)) - Draw part of the specified bitmap on the current ownerdraw/buffer canvas at the specified coordinates.
((setBitmapStretchTransparent)) - Draw a stretched or shrunk bitmap on the current ownerdraw/buffer canvas with a transparent color.

=== Shapes ===
((setAngleArc)) - Draws the outlines of a pie segment of a circle.
((setAngleArcFill)) - Draws a filled pie segment of a circle.
((setEllipse)) - draws an ellipse 
((setEllipseFill)) - draws a filled ellipse 
((setEndCaps)) - sets the method used to cap the ends of lines with the constants PS_ENDCAP_ROUND, PS_ENDCAP_SQUARE and PS_ENDCAP_FLAT. 
((setFill)) - fills the whole ownerdraw control with a certain color e.g. setFill(getCtlColor(n)) 
((setInsideFrame)) - determines whether the pen lines of shapes are drawn on the edge or inside the edge.
((setJoin)) - sets the method used to join thick lines at corners of shapes with the constants PS_JOIN_ROUND, PS_JOIN_BEVEL and PS_JOIN_MITER. 
((setLine)) - draws a line 
((setPenWidth)) - lets you change the broadness of drawn lines.
((setRectangle)) - draws a rectangle
((setRectFrame)) - draws a rectangle 
((setRectFill)) - draws a filled rectangle 
((setRectGradient)) - draws a gradient into the rectangle

=== Anti-aliased shapes ===
If you only need these shapes or non-anti-aliased shapes, these functions will be both faster and better quality than using SuperSampling mode.
((setThinLineAA)) - Draw anti-aliased line of one pixel width
((setThinEllipseAA)) - draw anti-aliased lines and ellipses
