* Clear the background with a color that includes an alpha value. This can
* only be used with objects created by createGraphics(), because the main
* drawing surface cannot be set transparent.
* It might be tempting to use this function to partially clear the screen
* on each frame, however that's not how this function works. When calling
* background(), the pixels will be replaced with pixels that have that
* level of transparency. To do a semi-transparent overlay, use fill() with
* alpha and draw a rectangle.
* If the image is in RGB format (i.e. on a PVideo object), the value will
* get its high bits set, just to avoid cases where they haven't been set
* already.
*
* If the image is in ALPHA format, this returns a white with its alpha
* value set.
*
* This function is included primarily for beginners. It is quite slow
* because it has to check to see if the x, y that was provided is inside
* the bounds, and then has to check to see what image type it is. If you

* Do not use variables as the parameters to size() function, because

* Instead, employ numeric values in the size()
* statement, and then use the built-in width and height
* variables inside your program when the dimensions of the display window
* are needed.
*
* The size() function can only be used once inside a sketch, and
* cannot be used for resizing.
* renderer parameter selects which rendering engine to use. For
* example, if you will be drawing 3D shapes, use P3D, if you want to
* export images from a program as a PDF file use PDF. A brief
* description of the three primary renderers follows:
*
* P2D (Processing 2D) - The default renderer that supports two
* dimensional drawing.
*
* P3D (Processing 3D) - 3D graphics renderer that makes use of
* OpenGL-compatible graphics hardware.
*
* PDF - The PDF renderer draws 2D graphics directly to an Acrobat
* PDF file. This produces excellent results when you need vector shapes for
* high resolution output or printing. You must first use Import Library
* → PDF to make use of the library. More information can be found in
* the PDF library reference.
*
* The P3D renderer doesn't support strokeCap() or
* strokeJoin(), which can lead to ugly results when using
* strokeWeight(). (Issue
* 123)
*
* The maximum width and height is limited by your operating system, and is
* usually the width and height of your actual screen. On some machines it
* may simply be the number of pixels on your current screen, meaning that a
* screen of 800x600 could support size(1600, 300), since it's the
* same number of pixels. This varies widely so you'll have to try different
* rendering modes and sizes until you get what you're looking for. If you
* need something larger, use createGraphics to create a non-visible
* drawing surface.
*
* Again, the size() function must be the first line of the code (or
* first item inside setup). Any code that appears before the size()
* command may run more than once, which can lead to confusing results.

* Called each time a single key on the keyboard is pressed. Because of how

* keyTyped with key == 'a' and keyCode == 0
* keyReleased with key == 'a' and keyCode == 'A'

* 2. Pressing 'A' on the keyboard:

* keyPressed with key == CODED and keyCode == SHIFT
* keyPressed with key == 'A' and keyCode == 'A'
* keyTyped with key == 'A' and keyCode == 0
* keyReleased with key == 'A' and keyCode == 'A'
* keyReleased with key == CODED and keyCode == SHIFT
*
* 4. Holding down the 'a' key.
* The following will happen several times,
* depending on your machine's "key repeat rate" settings:
* keyPressed with key == 'a' and keyCode == 'A'
* keyTyped with key == 'a' and keyCode == 0
* When you finally let go, you'll get:
* keyReleased with key == 'a' and keyCode == 'A'

// * random() function is that Perlin noise is defined in an infinite

// * semi-random value (fixed only for the lifespan of the program). The
// * resulting value will always be between 0.0 and 1.0. Processing can
// * compute 1D, 2D and 3D noise, depending on the number of coordinates
// * given. The noise value can be animated by moving through the noise space
// * as demonstrated in the example above. The 2nd and 3rd dimension can also
// * be interpreted as time.The actual noise is structured similar to an audio
// * signal, in respect to the function's use of frequencies. Similar to the
// * concept of harmonics in physics, perlin noise is computed over several
// * octaves which are added together for the final result. Another way to
// * adjust the character of the resulting sequence is the scale of the input
// * coordinates. As the function works within an infinite space the value of
// * the coordinates doesn't matter as such, only the distance between
// * successive coordinates does (eg. when using noise() within a
// * loop). As a general rule the smaller the difference between coordinates,
// * the smoother the resulting noise sequence will be. Steps of 0.005-0.03

*
* Like loadImage() and other functions that load data, the
* loadFont() function should not be used inside draw(),

* For most renderers, Processing displays fonts using the .vlw font format,

* installed on the user's machine.
*
* Using createFont() (instead of loadFont) enables vector data to be
* used with the JAVA2D (default) renderer setting. This can be helpful when
* many font sizes are needed, or when using any renderer based on JAVA2D,

*
* Dynamically converts a font to the format used by Processing from either
* a font name that's installed on the computer, or from a .ttf or .otf file
* inside the sketches "data" folder. This function is an advanced feature
* for precise control. On most occasions you should create fonts through
* selecting "Create Font..." from the Tools menu.
*
* Use the PFont.list() method to first determine the names for the
* fonts recognized by the computer and are compatible with this function.
* Because of limitations in Java, not all fonts can be used and some might
* work with one operating system and not others. When sharing a sketch with
* other people or posting it on the web, you may need to include a .ttf or
* .otf version of your font in the data directory of the sketch because
* other people might not have the font installed on their computer. Only
* fonts that can legally be distributed should be included with a sketch.
*
* The size parameter states the font size you want to generate. The
* smooth parameter specifies if the font should be antialiased or
* not, and the charset parameter is an array of chars that specifies
* the characters to generate.
*
* This function creates a bitmapped version of a font in the same manner as
* the Create Font tool. It loads a font by name, and converts it to a
* series of images based on the size of the font. When possible, the
* text() function will use a native font rather than the bitmapped
* version created behind the scenes with createFont(). For instance,
* when using P2D, the actual native version of the font will be employed by
* the sketch, improving drawing quality and performance. With the P3D
* renderer, the bitmapped version will be used. While this can drastically
* improve speed and appearance, results are poor when exporting if the
* sketch does not include the .otf or .ttf file, and the requested font is
* not available on the machine running the sketch.

* returned will be in RGB format.
*
* Getting the color of a single pixel with get(x, y) is easy, but
* not as fast as grabbing the data directly from pixels[]. The
* equivalent statement to get(x, y) using pixels[] is
* pixels[y*width+x]. See the reference for pixels[] for more

/**
* ( begin auto-generated from PImage_blend.xml )
*
* Blends a region of pixels into the image specified by the img
* parameter. These copies utilize full alpha channel support and a choice
* of the following modes to blend the colors of source pixels (A) with the
* ones of pixels in the destination image (B):
*
* BLEND - linear interpolation of colours: C = A*factor + B
*
* ADD - additive blending with white clip: C = min(A*factor + B, 255)
*
* SUBTRACT - subtractive blending with black clip: C = max(B - A*factor, 0)
*
* DARKEST - only the darkest colour succeeds: C = min(A*factor, B)
*
* LIGHTEST - only the lightest colour succeeds: C = max(A*factor, B)
*
* DIFFERENCE - subtract colors from underlying image.
*
* EXCLUSION - similar to DIFFERENCE, but less extreme.
*
* MULTIPLY - Multiply the colors, result will always be darker.
*
* SCREEN - Opposite multiply, uses inverse values of the colors.
*
* OVERLAY - A mix of MULTIPLY and SCREEN. Multiplies dark values, and
* screens light values.
*
* HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower.
*
* SOFT_LIGHT - Mix of DARKEST and LIGHTEST. Works like OVERLAY, but not as
* harsh.
*
* DODGE - Lightens light tones and increases contrast, ignores darks.
* Called "Color Dodge" in Illustrator and Photoshop.
*
* BURN - Darker areas are applied, increasing contrast, ignores lights.
* Called "Color Burn" in Illustrator and Photoshop.
*
* All modes use the alpha information (highest byte) of source image pixels
* as the blending factor. If the source and destination regions are
* different sizes, the image will be automatically resized to match the
* destination size. If the srcImg parameter is not used, the display
* window is used as the source image.
