1.1.4.1 update

* Removed unnecessary `UpdateStyles` calls.
* Changed the `ViewSize` property and `DrawImage` methods to handle
disposed images rather than bringing down an entire application.
* Added `TextFormatFlags.NoPadding` to the flags used by `DrawLabel` to
avoid a slight gap on left aligned text.
* Fixed a potential crash calling `GetSelectedImage`. Thanks to
MutStarburst for finding this bug.
