typedef HRESULT (WINAPI *LPD3DXUVATLASCB)(FLOAT fPercentDone, LPVOID lpUserContext);
// This function creates atlases for meshes. There are two modes of operation,
// either based on the number of charts, or the maximum allowed stretch. If the
// maximum allowed stretch is 0, then each triangle will likely be in its own
// chart.
//
// The parameters are as follows:
// pMesh - Input mesh to calculate an atlas for. This must have a position
// channel and at least a 2-d texture channel.
// uMaxChartNumber - The maximum number of charts required for the atlas.
// If this is 0, it will be parameterized based solely on
// stretch.
// fMaxStretch - The maximum amount of stretch, if 0, no stretching is allowed,
// if 1, then any amount of stretching is allowed.
// uWidth - The width of the texture the atlas will be used on.
// uHeight - The height of the texture the atlas will be used on.
// fGutter - The minimum distance, in texels between two charts on the atlas.
// this gets scaled by the width, so if fGutter is 2.5, and it is
// used on a 512x512 texture, then the minimum distance will be
// 2.5 / 512 in u-v space.
// dwTextureIndex - Specifies which texture coordinate to write to in the
// output mesh (which is cloned from the input mesh). Useful
// if your vertex has multiple texture coordinates.
// pdwAdjacency - a pointer to an array with 3 DWORDs per face, indicating
// which triangles are adjacent to each other.
// pdwFalseEdgeAdjacency - a pointer to an array with 3 DWORDS per face, indicating
// at each face, whether an edge is a false edge or not (using
// the same ordering as the adjacency data structure). If this
// is NULL, then it is assumed that there are no false edges. If
// not NULL, then a non-false edge is indicated by -1 and a false
// edge is indicated by any other value (it is not required, but
// it may be useful for the caller to use the original adjacency
// value). This allows you to parameterize a mesh of quads, and
// the edges down the middle of each quad will not be cut when
// parameterizing the mesh.
// pfIMTArray - a pointer to an array with 3 FLOATs per face, describing the
// integrated metric tensor for that face. This lets you control
// the way this triangle may be stretched in the atlas. The IMT
// passed in will be 3 floats (a,b,c) and specify a symmetric
// matrix (a b) that, given a vector (s,t), specifies the
// (b c)
// distance between a vector v1 and a vector v2 = v1 + (s,t) as
// sqrt((s, t) * M * (s, t)^T).
// In other words, this lets one specify the magnitude of the
// stretch in an arbitrary direction in u-v space. For example
// if a = b = c = 1, then this scales the vector (1,1) by 2, and
// the vector (1,-1) by 0. Note that this is multiplying the edge
// length by the square of the matrix, so if you want the face to
// stretch to twice its
// size with no shearing, the IMT value should be (2, 0, 2), which
// is just the identity matrix times 2.
// Note that this assumes you have an orientation for the triangle
// in some 2-D space. For D3DXUVAtlas, this space is created by
// letting S be the direction from the first to the second
// vertex, and T be the cross product between the normal and S.
//
// pStatusCallback - Since the atlas creation process can be very CPU intensive,
// this allows the programmer to specify a function to be called
// periodically, similarly to how it is done in the PRT simulation
// engine.
// fCallbackFrequency - This lets you specify how often the callback will be
// called. A decent default should be 0.0001f.
// pUserContext - a void pointer to be passed back to the callback function
// dwOptions - A combination of flags in the D3DXUVATLAS enum
// ppMeshOut - A pointer to a location to store a pointer for the newly created
// mesh.
// ppFacePartitioning - A pointer to a location to store a pointer for an array,
// one DWORD per face, giving the final partitioning
// created by the atlasing algorithm.
// ppVertexRemapArray - A pointer to a location to store a pointer for an array,
// one DWORD per vertex, giving the vertex it was copied
// from, if any vertices needed to be split.
// pfMaxStretchOut - A location to store the maximum stretch resulting from the
// atlasing algorithm.
// puNumChartsOut - A location to store the number of charts created, or if the
// maximum number of charts was too low, this gives the minimum
// number of charts needed to create an atlas.
