* app/transform_core.c (transform_core_cut): when transforming
a selection in an indexed image, we used to create an indexed
tile_buffer. This gives strange (black) results later when we
use layer_new_from_tiles() since that function assumes that a
TileManager is always RGB or GRAY. Eeek!!

Instead of fixing it correctly by changing the TileManager
struct, I've unset the keep_indexed flag when calling
gimage_mask_extract(), so whatever layer_new_from_tiles()
assumes becomes true. Fixes bug #10762.
