12Subject: [PATCH] Manually transpose the matrix in _cairo_gl_shader_bind_matrix()
13
14To maintain compatibility with OpenGL ES 2.0, the matrix in
15_cairo_gl_shader_bind_matrix() should be manually transposed,
16and GL_FALSE passed as the transpose argument to the
17glUniformMatrix3fv() call as it is the only valid value for
18that parameter in OpenGL ES 2.0.
