Add the possibility to set a 4x4 matrix to be used on blf.

This option allow the user to set a 4x4 matrix to be
multiplied before draw the text, for example:

	double *m;

	/* Get the matrix or build it! */

	BLF_matrix(m);
	BLF_enable(BLF_MATRIX);

	/* set color, size, etc and draw! */

	BLF_disable(BLF_MATRIX);

You don't need the last line (disable), but remember
that if you use the font to draw in any other place,
the matrix will be used!.

The GL code is:

	glPushMatrix();
	glMultMatrixd(m);
	glTranslatef();
	glScalef();
	glRotatef();

	glPopMatrix();

Let's Dalai test this!!! :D
