// Just replace this file with new defines if necessary.
// For example, if your compiler doesn't have a 64 bit integer type
// you can still use AGG if you define the follows:
//
// #define AGG_INT64 int
// #define AGG_INT64U unsigned
//
// It will result in overflow in 16 bit-per-component image/pattern resampling
// but it won't result any crash and the rest of the library will remain
// fully functional.

// 2. Default rendering_buffer type. Can be:
//
// Provides faster access for massive pixel operations,
// such as blur, image filtering:
// #define AGG_RENDERING_BUFFER row_ptr_cache<int8u>
//
// Provides cheaper creation and destruction (no mem allocs):
// #define AGG_RENDERING_BUFFER row_accessor<int8u>
//
// You can still use both of them simultaneously in your applications
// This #define is used only for default rendering_buffer type,
// in short hand typedefs like pixfmt_rgba32.

// Polygon rasterizer that is used to render filled polygons with
// high-quality Anti-Aliasing. Internally, by default, the class uses
// 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".
//

// row_accessor is cheap to create/destroy, but performs one multiplication
// when calling row_ptr().
//
// row_ptr_cache creates an array of pointers to rows, so, the access
// via row_ptr() may be faster. But it requires memory allocation
// when creating. For example, on typical Intel Pentium hardware
// row_ptr_cache speeds span_image_filter_rgb_nn up to 10%
//
// It's used only in short hand typedefs like pixfmt_rgba32 and can be
// redefined in agg_config.h
// In real applications you can use both, depending on your needs

//============================================================trans_affine
//
// See Implementation agg_trans_affine.cpp
//
// Affine transformation are linear transformations in Cartesian coordinates
// (strictly speaking not only in Cartesian, but for the beginning we will
// think so). They are rotation, scaling, translation and skewing.
// After any affine transformation a line segment remains a line segment
// and it will never become a curve.
//
// There will be no math about matrix calculations, since it has been
// described many times. Ask yourself a very simple question:
// "why do we need to understand and use some matrix stuff instead of just
// rotating, scaling and so on". The answers are:
//
// 1. Any combination of transformations can be done by only 4 multiplications
// and 4 additions in floating point.
// 2. One matrix transformation is equivalent to the number of consecutive
// discrete transformations, i.e. the matrix "accumulates" all transformations
// in the order of their settings. Suppose we have 4 transformations:
// * rotate by 30 degrees,
// * scale X to 2.0,
// * scale Y to 1.5,
// * move to (100, 100).
// The result will depend on the order of these transformations,
// and the advantage of matrix is that the sequence of discret calls:
// rotate(30), scaleX(2.0), scaleY(1.5), move(100,100)
// will have exactly the same result as the following matrix transformations:
//
// affine_matrix m;
// m *= rotate_matrix(30);
// m *= scaleX_matrix(2.0);
// m *= scaleY_matrix(1.5);
// m *= move_matrix(100,100);
//
// m.transform_my_point_at_last(x, y);
//
// What is the good of it? In real life we will set-up the matrix only once
// and then transform many points, let alone the convenience to set any
// combination of transformations.
//
// So, how to use it? Very easy - literally as it's shown above. Not quite,
// let us write a correct example:
//
// agg::trans_affine m;
// m *= agg::trans_affine_rotation(30.0 * 3.1415926 / 180.0);
// m *= agg::trans_affine_scaling(2.0, 1.5);
// m *= agg::trans_affine_translation(100.0, 100.0);
// m.transform(&x, &y);
//
// The affine matrix is all you need to perform any linear transformation,
// but all transformations have origin point (0,0). It means that we need to
// use 2 translations if we want to rotate someting around (100,100):
//
// m *= agg::trans_affine_translation(-100.0, -100.0); // move to (0,0)
// m *= agg::trans_affine_rotation(30.0 * 3.1415926 / 180.0); // rotate
// m *= agg::trans_affine_translation(100.0, 100.0); // move back to (100,100)

* This module provides an interface to the Cholmod library which is part of the <a href="http://www.suitesparse.com">suitesparse</a> package.
* It provides the two following main factorization classes:
* - class CholmodSupernodalLLT: a supernodal LLT Cholesky factorization.
* - class CholmodDecomposiiton: a general L(D)LT Cholesky factorization with automatic or explicit runtime selection of the underlying factorization method (supernodal or simplicial).
*
* For the sake of completeness, this module also propose the two following classes:
* - class CholmodSimplicialLLT
* - class CholmodSimplicialLDLT
* Note that these classes does not bring any particular advantage compared to the built-in
* SimplicialLLT and SimplicialLDLT factorization classes.
*
* \code
* #include <Eigen/CholmodSupport>
* \endcode
*
* In order to use this module, the cholmod headers must be accessible from the include paths, and your binary must be linked to the cholmod library and its dependencies.
* The dependencies depend on how cholmod has been compiled.
* For a cmake based project, you can use our FindCholmod.cmake module to help you in this task.

* - ConjugateGradient for selfadjoint (hermitian) matrices,
* - LeastSquaresConjugateGradient for rectangular least-square problems,

* These iterative solvers are associated with some preconditioners:

* - DiagonalPreconditioner - also called Jacobi preconditioner, work very well on diagonal dominant matrices.
* - IncompleteLUT - incomplete LU factorization with dual thresholding

/**
* \defgroup OrderingMethods_Module OrderingMethods module
*
* This module is currently for internal use only
*
* It defines various built-in and external ordering methods for sparse matrices.
* They are typically used to reduce the number of elements during
* the sparse matrix decomposition (LLT, LU, QR).
* Precisely, in a preprocessing step, a permutation matrix P is computed using
* those ordering methods and applied to the columns of the matrix.
* Using for instance the sparse Cholesky decomposition, it is expected that
* the nonzeros elements in LLT(A*P) will be much smaller than that in LLT(A).
*
*
* Usage :
* \code
* #include <Eigen/OrderingMethods>
* \endcode
*
* A simple usage is as a template parameter in the sparse decomposition classes :
*
* \code
* SparseLU<MatrixType, COLAMDOrdering<int> > solver;
* \endcode
*
* \code
* SparseQR<MatrixType, COLAMDOrdering<int> > solver;
* \endcode
*
* It is possible as well to call directly a particular ordering method for your own purpose,
* \code
* AMDOrdering<int> ordering;
* PermutationMatrix<Dynamic, Dynamic, int> perm;
* SparseMatrix<double> A;
* //Fill the matrix ...
*
* ordering(A, perm); // Call AMD
* \endcode
*
* \note Some of these methods (like AMD or METIS), need the sparsity pattern
* of the input matrix to be symmetric. When the matrix is structurally unsymmetric,
* Eigen computes internally the pattern of \f$A^T*A\f$ before calling the method.
* If your matrix is already symmetric (at leat in structure), you can avoid that
* by calling the method with a SelfAdjointView type.
*
* \code
* // Call the ordering on the pattern of the lower triangular matrix A
* ordering(A.selfadjointView<Lower>(), perm);
* \endcode
