* Note:
* =====
* tulipIP has 2 extended methods of every filter make it able to
* to do it's work in part of the given gd resource
* example:
* tulip has filter named (gray) to add grayscale effect for the given gd resource
* also has :
* method named (gray_part) to apply gray filter for the selected area
* of the given gd resource only .
* also has :
* method named (gray_invert) to apply gray filter for the given gd resource
* except the selected area
*
* and so on
*
* Filter Extended Part Extended Invert
* ======== =============== =======================
* gray() gray_part() gray_invert()
* negate() negate_part() negate_invert()
* brightness() brightness_part() brightness_invert()
* contrast() contrast_part() contrast_invert()
* colorize() colorize_part() colorize_invert()
* Gblur() Gblur_part() Gblur_invert()
* gamma() gamma_part() gamma_invert()
* edge() edge_part() edge_invert()
* emboss() emboss_part() emboss_invert()
* light() light_part() light_invert()
* flip() flip_part() flip_invert()
*
* All (Extended Part) And (Extended Invert) Methods
* share the params :
* 1- virtual_image -> gd resource
* 2- $x -> x coordinate to start point
* 3- $y -> y coordinate to start point
* 4- $width -> end x coordinate
* 5- $height -> end y coordinate
