- * This class implements a dynamically sized container, which
- * can be accessed similar to a regular C++ array. Accessing
- * elements is performed in constant time (like with plain arrays).
- * In addition, one can append, insert and remove entries (this
- * is the 'dynamic' part). Doing that in general takes time
- * proportional to the number of elements in the array.
- *
- * The container class closest to this in the C++ standard library is
- * std::vector. However, there are some differences. The most important one is
- * that std::vector has a far more sophisticated (and complicated) memory
- * management scheme. There, only elements that 'live' are actually constructed
- * (i.e., have their constructor called), and objects that are removed are
- * immediately destructed (have their destructor called).
- * With Common::Array, this is not the case; instead, it simply uses new[] and
- * delete[] to allocate whole blocks of objects, possibly more than are
- * currently 'alive'. This simplifies memory management, but may have
- * undesirable side effects when one wants to use an Array of complex
- * data types.
- *
- * @todo Improve the storage management of this class.
- * In particular, don't use new[] and delete[], but rather
- * construct/destruct objects manually. This way, we can
- * ensure that storage which is not currently used does not
- * correspond to a live active object.
- * (This is only of interest for array of non-POD objects).

- stored in the callback's private data and incremented on each
- call).
-
- The rendered polygon is represented in a semi-runlength format: a
- start value and a sequence of "steps". Each step has an x
- coordinate and a value delta. The resulting value at position x is
- equal to the sum of the start value and all step delta values for
- which the step x coordinate is less than or equal to x. An
- efficient algorithm will traverse the steps left to right, keeping
- a running sum.
-
- All x coordinates in the steps are guaranteed to be x0 <= x < x1.
- (This guarantee is a change from the gfonted vpaar renderer, and is
- designed to simplify the callback).
-
- There is now a further guarantee that no two steps will have the
- same x value. This may allow for further speedup and simplification
- of renderers.
-
- The value 0x8000 represents 0% coverage by the polygon, while
- 0xff8000 represents 100% coverage. This format is designed so that
- >> 16 results in a standard 0x00..0xff value range, with nice
- rounding.
-
- Status of this routine:
-
- Basic correctness: OK
-
- Numerical stability: pretty good, although probably not
- bulletproof.
-
- Speed: Needs more aggressive culling of bounding boxes. Can
- probably speed up the [x0,x1) clipping of step values. Can do more
- of the step calculation in fixed point.
-
- Precision: No known problems, although it should be tested
- thoroughly, especially for symmetry.

- * art_svp_vpath_stroke: Stroke a vector path.

- * @cap: Cap style.
- * @line_width: Width of stroke.
- * @miter_limit: Miter limit.
- * @flatness: Flatness.
- *
- * Computes an svp representing the stroked outline of @vpath. The
- * width of the stroked line is @line_width.
- *
- * Lines are joined according to the @join rule. Possible values are
- * ART_PATH_STROKE_JOIN_MITER (for mitered joins),
- * ART_PATH_STROKE_JOIN_ROUND (for round joins), and
- * ART_PATH_STROKE_JOIN_BEVEL (for bevelled joins). The mitered join
- * is converted to a bevelled join if the miter would extend to a
- * distance of more than @miter_limit * @line_width from the actual
- * join point.
- *
- * If there are open subpaths, the ends of these subpaths are capped
- * according to the @cap rule. Possible values are
- * ART_PATH_STROKE_CAP_BUTT (squared cap, extends exactly to end
- * point), ART_PATH_STROKE_CAP_ROUND (rounded half-circle centered at
- * the end point), and ART_PATH_STROKE_CAP_SQUARE (squared cap,
- * extending half @line_width past the end point).
- *
- * The @flatness parameter controls the accuracy of the rendering. It
- * is most important for determining the number of points to use to
- * approximate circular arcs for round lines and joins. In general, the
- * resulting vector path will be within @flatness pixels of the "ideal"
- * path containing actual circular arcs. I reserve the right to use
- * the @flatness parameter to convert bevelled joins to miters for very
- * small turn angles, as this would reduce the number of points in the
- * resulting outline path.
- *
- * The resulting path is "clean" with respect to self-intersections, i.e.
- * the winding number is 0 or 1 at each point.
- *
- * Return value: Resulting stroked outline in svp format.

-/**
- * Generic functor object for unary function objects.
- *
- * A typical usage for an unary function object is for executing opcodes
- * in a script interpreter. To achieve that one can create an Common::Array
- * object with 'Functor1<Arg, Res> *' as type. Now after the right engine version
- * has been determined and the opcode table to use is found one could easily
- * add the opcode implementations like this:
- *
- * Common::Array<Functor1<ScriptState, void> *> opcodeTable;
- * opcodeTable[0] = new Functor1Mem<ScriptState, void, MyEngine_v1>(&myEngine, &MyEngine_v1::o1_foo);
- * opcodeTable[1] = new Functor1Mem<ScriptState, void, MyEngine_v2>(&myEngine, &MyEngine_v2::o2_foo);
- * // unimplemented/unused opcode
- * opcodeTable[2] = 0;
- * etc.
- *
- * This makes it easy to add member functions of different classes as
- * opcode functions to the function table. Since with the generic
- * Functor1<ScriptState, void> object the only requirement for an
- * function to be used is 'ScriptState' as argument and 'void' as return
- * value.
- *
- * Now for calling the opcodes one has simple to do:
- * if (opcodeTable[opcodeNum] && opcodeTable[opcodeNum]->isValid())
- * (*opcodeTable[opcodeNum])(scriptState);
- * else
- * warning("Unimplemented opcode %d", opcodeNum);
- *
- * If you want to see an real world example check the kyra engine.
- * Files: engines/kyra/script.cpp and .h and engines/kyra/script_*.cpp
- * are interesting for that matter.
