153f5ea73f Bug 1189 - Backface culling
* clutter/cogl/gl/cogl-texture.c (cogl_texture_polygon)
	(_cogl_texture_quad_sw, _cogl_texture_quad_hw):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_polygon)
	(_cogl_texture_quad_sw, _cogl_texture_quad_hw): Enable backface
	culling in GL if it is requested.

	* clutter/cogl/gles/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw):
	* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw): Reorder the
	vertices so that they are counter-clockwise.

	* clutter/cogl/gles/cogl-context.h (CoglContext): 
	* clutter/cogl/gl/cogl-context.h (CoglContext): Added a flag to
	store whether backface culling is currently enabled.

	* clutter/cogl/gl/cogl.c (cogl_enable_backface_culling): New

eccd9399e5 * clutter/cogl/gl/cogl.c (error_string):
* clutter/cogl/gles/cogl.c (error_string): Rename to
	_cogl_error_string and remove the static scoping so that it can be
	called in cogl-texture etc.

	* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_new_from_foreign):
	GE(*) can't be used to wrap around calls that use the return
	value.

	* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw, cogl_texture_polygon): Remove GE(*)
	wrapper around calls in the middle of a glBegin/glEnd pair which
	otherwise always generate an error because glGetError can only be
	called outside of the pair.

	* clutter/cogl/gl/cogl-internal.h: Include stdio.h when definig
	COGL_DEBUG and declare a prototype for _cogl_error_string.

	* clutter/cogl/gles/cogl-internal.h: Match GE(*) macro to GL
	version.

006573ac61 * clutter/cogl/gles/cogl-texture.c:
(cogl_texture_download_from_gl:) Store old blending factors
	and restore them when done. The lack of ability to retrieve
	the alpha channel now more noticable in test-cogl-tex-getset
	since the edges of the hand are not antialiased.

	* clutter/cogl/gl(es)/cogl-internal.h: Declare
	cogl_blend_func to avoid "implicit implementation" compile
	warning.
