ortho

Description:

public void ortho (float left, float right, float bottom, float top, float z_near, float z_far)

Multiplies this by a parallel projection matrix.

Note:

Use cogl_matrix_orthographic

this	A 4x4 transformation matrix
left	The coordinate for the left clipping plane
right	The coordinate for the right clipping plane
bottom	The coordinate for the bottom clipping plane
top	The coordinate for the top clipping plane
far	The `distance` to the far clipping plane (will be `negative` if the plane is behind the viewer)
near	The `distance` to the near clipping plane (will be `negative` if the plane is behind the viewer)
