* BUG: Some little layout fixes. [INTERPRETER] * OPT: Read the user home directory only if the current uid has changed. Otherwise, cache it into memory. * OPT: String memory management has been optimized. * OPT: Some little optimizations there and there. * NEW: A new interpreter option, "-k", that prevents shared library to be unloaded until the process terminates. That can be useful when debugging with valgrind. * OPT: System.Language property was optimized. * OPT: The gb_error.c file is now compiled with -O3. [GB.GTK] * BUG: Disable the management of input methods in TextBox and TextArea controls, so that the input methods are not disturbed. Consequently; SCIM and Bridged SCIM work again. * BUG: You can read keyboard events properties in a Form KeyPress or KeyRelease event handler correctly now. git-svn-id: svn://localhost/gambas/trunk@1199 867c0c6c-44f3-4631-809d-bfa615b0a4ec
