Art of scening is how a painting is presented to the audience. With no scening the canvas is shown as is. It develops from nothing just as it's designed in paint scenario. Taking advantage of scening, authors affect to the picture with no actual impact to the canvas. Scening is a proxy between the canvas and the viewer.

Scening reproduces the moments when canvas is beautiful and hides it when it goes through an "awkward stage". It adjusts the colors when it's needed. It reduces luminosity when it's too bright or gains it up when it's flat. It performs a fade-in on beginning of the action and fades the picture out at the end of scenario.

Scening is synchronized with the paint scenario and runs simultaneously with it. Like painting, it is an iterative process. It can be either finite or may go on perpetually. Its sequence is defined by the hierarchy of nested loops. A top-level loop starts with scene keyword followed by number of iterations. Each scene block must be closed with end keyword. The contents of a loop should conform the syntax below.

Scene	number of iterations
Show duration Shade duration Screen duration Fade-out parameters... Flash parameters... Set assigns a value to variable Scene length of the nested loop ... End
End

# In this example a "bloody" flash 
# effect happens at the end of 
# "Kabala Magnet" painting.
