* 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.
