Creates and initializes a Matrix object that represents the identity matrix
#include <GDIPlus.au3>
_GDIPlus_MatrixCreate ( )
| Success: | a handle to a Matrix object. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
When you are done with the matrix, call _GDIPlus_MatrixDispose() to release the resources.
