Sun Mar 22 16:25:46 1998 Owen Taylor <owt1@cornell.edu> * gtk/gtkmain.c (gtk_init): fixes to locale checks * gtk/testgtk.c (create_dnd): Create the dnd icons separately to avoid strange interactions with shapes demo. * gtk/gtkentry.[ch]: - Limit the length of the text to 2048 to prevent long delays - Fix problems with buffer overruns - Draw only the onscreen portion of the text to prevent wrapping of shorts in the X drawing code. - Keep track of character positions and x-offsets to speed up algorithms.
