Builds a left-handed orthogonal projection matrix.
D3DXMATRIX* D3DXMatrixOrthoLH( D3DXMATRIX* pOut, FLOAT w, FLOAT h, FLOAT zn, FLOAT zf );
Pointer to a D3DXMATRIX structure that is a left-handed orthogonal projection matrix.
An orthogonal matrix is an invertible matrix for which the inverse of the matrix is equal to the transpose of the matrix.
All the parameters of the D3DXMatrixOrthoLH function are distances in camera-space. The parameters describe the dimensions of the view-volume.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixOrthoLH function can be used as a parameter for another function.
