	* clutter/cogl/gl(es)/cogl-texture.c:
	cogl_texture_new_* functions take a gboolean auto_mipmap argument.
	If TRUE automatic mipmap generation is enabled during the process
	of slice texture object creation.
	(cogl_texture_new_from_foreign:) now allows mipmap min filter
	flags.

	Pass FALSE for auto_mipmap to cogl_texture_new_*.

	(tc_get:) Pass TRUE to cogl_texture_new_with_size and use mipmap
	min filter for nicer glyphs at small scales. As a result test-text
	has gone all beautiful now.
