* clutter/cogl/cogl.h.in:
* clutter/cogl/gl(es)/cogl-texture.h: * 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. * clutter/clutter-texture.c: * clutter/glx/clutter-glx-texture-pixmap.c: * tests/test-cogl-offscreen.c: * tests/test-cogl-tex-tile.c: * tests/test-cogl-tex-convert.c: * tests/test-cogl-tex-polygon.c: * tests/test-cogl-tex-getset.c: Pass FALSE for auto_mipmap to cogl_texture_new_*. * clutter/pango/pangoclutter-render.c: (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.
