PRICE - image filtering and manipulation Code

size exactly 255x255

make view exactly 255 px wide and hight, make the view resizable

use max normal size for calculation, transformation is applied later, the size is not important anymore

use a macro to define control point rects and make them 2 pixels larger

fix resizing and calculation of the affinte transform, use bounds for it; reset the curve transformation when resetting it

Allow the curves's total transformation to be reset

make initial view actually 255x255

draw curves after histograms, so that they don't overlap

correctly move control points of black point

take in account of scaled values when setting white and black point
