CairoMatrix::scale - Applies scaling to a matrix

       Object oriented style (method):

SYNOPSIS
       public void CairoMatrix::scale (float  $sx, float  $sy)

DESCRIPTION
       Procedural style:
       void cairo_matrix_scale (CairoContext  $context, float  $sx, float  $sy)

	Applies  scaling  by sx, sy to the transformation in the matrix. The effect of the new transformation is to first scale the coordinates by
       sx and sy, then apply the original transformation to the coordinates.

PARAMETERS
	      o $matrix
		- Procedural only - CairoMatrix instance

	      o $sx
		- scale factor in the X direction

	      o $sy
		- scale factor in the Y direction

EXAMPLES
       Example #1

	      Object oriented style

	      <?php
	      /* Apply scaling to a matrix */
	      $matrix = new CairoMatrix(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
	      $matrix->scale(0.2, 2.0);
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Apply scaling to a matrix */
	      $matrix = cairo_matrix_init(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
	      cairo_matrix_scale($matrix, 0.2, 2.0);
	      ?>
