// are marked with special commands. So, if the path_storage contains curves

// integer coordinates in format 24.8, i.e. 24 bits for integer part
// and 8 bits for fractional - see poly_subpixel_shift. This class can be
// used in the following way:
//
// 1. filling_rule(filling_rule_e ft) - optional.
//
// 2. gamma() - optional.
//
// 3. reset()
//
// 4. move_to(x, y) / line_to(x, y) - make the polygon. One can create
// more than one contour, but each contour must consist of at least 3
// vertices, i.e. move_to(x1, y1); line_to(x2, y2); line_to(x3, y3);
// is the absolute minimum of vertices that define a triangle.
// The algorithm does not check either the number of vertices nor
// coincidence of their coordinates, but in the worst case it just
// won't draw anything.
// The orger of the vertices (clockwise or counterclockwise)
// is important when using the non-zero filling rule (fill_non_zero).
// In this case the vertex order of all the contours must be the same
// if you want your intersecting polygons to be without "holes".
// You actually can use different vertices order. If the contours do not
// intersect each other the order is not important anyway. If they do,
// contours with the same vertex order will be rendered without "holes"
// while the intersecting contours with different orders will have "holes".

// This class is used to transfer data from a scanline rasterizer

// Each span has staring X, length, and an array of bytes that determine the
// cover-values for each pixel.
// Before using this class you should know the minimal and maximal pixel
// coordinates of your scanline. The protocol of using is:
// 1. reset(min_x, max_x)
// 2. add_cell() / add_span() - accumulate scanline.
// When forming one scanline the next X coordinate must be always greater
// than the last stored one, i.e. it works only with ordered coordinates.
// 3. Call finalize(y) and render the scanline.
// 3. Call reset_spans() to prepare for the new scanline.
//
// 4. Rendering:
//
// Scanline provides an iterator class that allows you to extract
// the spans and the cover values for each pixel. Be aware that clipping
// has not been done yet, so you should perform it yourself.
// Use scanline_u8::iterator to render spans:

//
// int num_pix = span->len; // Number of pixels of the span.

// // better to use "int" instead of
// // "unsigned" because it's more
// // convenient for clipping
// int x = span->x;

// The question is: why should we accumulate the whole scanline when we
// could render just separate spans when they're ready?
// That's because using the scanline is generally faster. When is consists
// of more than one span the conditions for the processor cash system
// are better, because switching between two different areas of memory
