              which defines the object's transparency level, 0 means totally
              transparent, while 255 means opaque. These color values are
              premultiplied by the alpha value.

              Usually youll use this attribute for text and rectangle objects,
              where the main color is their unique one. If set for objects
              which themselves have colors, like the images one, those colors
              get modulated by this one.

              All newly created Evas rectangles get the default color
              values of 255 255 255 255 (opaque white).

              Use null pointers on the components you're not interested
              in: they'll be ignored by the function.

           showing it. Note that this behavior is new since 1.21, and only
           applies to canvas objects created with the EO API (i.e. not the
           legacy C-only API). Other types of Gfx objects may or may not be
           visible by default.

           Note that many other parameters can prevent a visible object from
           actually being "visible" on screen. For instance if its color
           is fully transparent, or its parent is hidden, or it is clipped out,
           etc...
