Deep shader refactoring for the following purposes: * used pre-calculated gradient texture instead of per-pixel gradient map computation * used HW wrap samples for fill spread setting * unified gradient shader types * used single shader module for composition instead of signle module per composition type * used single shader module for blending for each of fill type (solid, gradient, image) instaed of signle module per blend type * much easier add new composition and blend equations * get rided std::string uasge * shaders code is more readable
