   offset matrix in .x file
  a skeletion has a pose ,each bone has offset matrix .but I found the info is not store in frame hierarchy.Frame pidaikou1 {   FrameTransformMatrix {1.000000,0.000000,0.000000,0.000000,0.000000,1.000000,-0.000000,0.000000,0.000000,0.000000,1.000000,0.000000,0.000000,0.000000,-0.000000,1.000000;; }Mesh pidaikou11 { 692;-0.009922;0.186933;-1.064720;,0.041236;0.174135;-1.088625;,0.051626;0.186694;-1.085097;,0.003653;0.199930;-1.061313;,0.063302;0.175198;-1.013270;,0.056523;0.146237;-1.016888;,0.026258;0.152983;-1.003180;,0.033416;0.183536;-0.999343;,-0.043077;0.190233;-1.000443;,-0.00992.........it seem to store in weight.template SkinWeights { <6f0d123b-bad2-4167-a0d0-80224f25fabb> STRING transformNodeName; DWORD nWeights; array DWORD vertexIndices[nWeights]; array FLOAT weights[nWeights]; Matrix4x4 matrixOffset;}where the hell it store?   
  The offset matrix is at the bottom of the SkinWeights template in the .x file.template SkinWeights { <6f0d123b-bad2-4167-a0d0-80224f25fabb> STRING transformNodeName; DWORD nWeights; array DWORD vertexIndices[nWeights]; array FLOAT weights[nWeights]; Matrix4x4 matrixOffset; <----------  (HERE)
