* Uses WP's Image Editor Class to crop and resize images.

* @link https://github.com/bfintal/bfi_thumb/pull/13
* Also incorporates positional cropping and image quality change from the Dominic Whittle bfithumb fork:
* @link https://github.com/dominicwhittle/bfi_thumb
* Crop mode support was inspired by TimThumb.
* @link http://www.binarymoon.co.uk/projects/timthumb/
*
* bfiThumb was inspired by Aqua Resizer
* @url https://github.com/syamilmj/Aqua-Resizer
*
* @todo Should an option be added to control the order filters should be applied be added? Filter order can affect result...
*
* Accepted option for the $atts property are:
* width (int|string) Width in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
* height (int|string) Height in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
*
* negate (bool) Whether or not to apply the negate filter. Default: FALSE
* grayscale (bool) Whether or not to apply the grayscale filter. Default: FALSE
* brightness (int) Adjust the image brightness. Valid range is -255–255 (-255 = min brightness, 0 = no change, +255 = max brightness). Default: 0
* colorize (string) Colorize the image. Either a valid hex-color #000000–#ffffff or a HTML named color like `red` can be supplied. Default: NULL
* @see cnColor::$colors for a list of valid named colors.
* contrast (int) Ajust the image contrast. Valid range is -100–100 (-100 = max contrast, 0 = no change, +100 = min contrast [note the direction]) Default: 0
* detect_edges (bool) Whether of not to apply the detect edges filter. Default: FALSE
* emboss (bool) Whether or not to apply the emboss filter. Default: FALSE
* gassian_blur (bool) Whether of not to apply a gaussian blur. Default: FALSE
* blur (bool) Whether or not to apply the blur filter. Default: FALSE
* sketchy (bool) Whether or not to apply the the skethy filter. Default: FALSE
* sharpen (bool) Whether or not to apply the sharpen filter. Default: FALSE
* smooth (int) Apply the smooth filter. Valid range is -100–100 (-100 = max smooth, 100 = min smooth). Default: NULL
* opacity (int) Set the image opacity. Valid range is 0–100 (0 = fully transparent, 100 = fully opaque). Default: 100
*
* crop_mode (int) Which crop mode to utilize when rescaling the image. Valid range is 0–3. Default: 1
* 0 == Resize to Fit specified dimensions with no cropping. Aspect ratio will not be maintained.
* 1 == Crop and resize to best fit dimensions maintaining aspect ration. Default.
* 2 == Resize proportionally to fit entire image into specified dimensions, and add margins if required.
* Use the canvas_color option to set the color to be used when adding margins.
* 3 == Resize proportionally adjusting size of scaled image so there are no margins added.
* crop_focus (array|string) The crop focus/positional cropping is used to determine the center origin of a crop when crop_mode is set 1.
* Valid range is (float) 0.0–1.0
* Default: array( .5, .5)
* Text options are also supported:
* 'left,top' | array( 'left', 'top' ) == array( 0, 0 )
* 'center,top' | array( 'center', 'top' ) == array( .5, 0 )
* 'right,top' | array( 'right', 'top' ) == array( 1, 0 )
* 'left,center' | array( 'left', 'center' ) == array( 0, .5 )
* 'center,center' | array( 'center', 'center' ) == array( .5, .5) [the default crop focus].
* 'right,center' | array( 'right', 'center' ) == array( 1, .5 )
* 'left,bottom' | array( 'left', 'bottom' ) == array( 0, 1 )

* crop_only (bool) Whether or not to just crop the image.
* If set to TRUE, crop_x, crop_y, crop_width, crop_height must be supplied.
* This overrides crop_mode.
* Default: FALSE
* crop_x (int|string) The x-axis crop origin start in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
* crop_y (int|string) The y-axis crop origin start in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
* crop_width (int|string) The resize width of the crop in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
* The width option can be set to determine the final scaled width.
* crop_height (int|string) The resize height of the crop in pixels or percentage. If using percentage, the percentage symbol must be included, example `50%`.
* The height option can be set to determine the final scaled height.
*
* canvas_color (string) Either a valid hex-color #000000–#ffffff or a HTML named color like `red` can be supplied or set to 'transparent'.
* The canvas_color is only used when using crop_mode=2. This will be the color of the margins.
* Default: #FFFFFF
* @see cnColor::$colors for a list of valid named colors.
*
* quality (int) The image quality to be used when saving the image. Valid range is 1–100. Default: 90
*
* @param string $source The local image path or URL to process. The image must be in the upload folder or the theme folder.
* @param array $atts An associative array containing the options used to process the image.
* @param string $return
*
* @return mixed array | object | string | stream
* If $return is `base64` then base64 encoded image data URI will be returned. Suitable for use in CSS or img src attribute.
* If $return is `data` and array of the image meta is returned.
* If $return is `editor` an instance if the WP_Image_Editor is returned.
* If $return is `stream` the image resource will be streamed to the browser with the correct headers set.
* If $return is `url` the image URL will be returned. [Default]
