Description Tim Buschtoens

ClientScripting should support the SWT.Paint event at least on Canvas. Other controls if possible. The GC field of the event will have a subset of the HTML5 canvas-gc API, NOT the SWT canvas-gc API.

Added basic paint event with commit f9fb389cdb59e1a976013e83aa33414c1a69589a.
Bug stays open until issues related to Bug 387034 are closed.

With commit 379b782ef8e5b49386d121e7e26749211ec5d0ed the server-side GC is re-used. However, this is not working with 1.5.0. The GC is now also initialized with the widgets colors and font. 

Another issue that has to be resolved is that a server-side paint event has to also trigger the client-side listener. Currently only a client-side call to "redraw" on the widget-proxy triggers the client-side paint listener.

With commit e63ffd0f3e6ed99297fb6656f1be52ec69c1d516 paint events are triggered via the "init" function on GC, called by the server.

However, this is still not working with 1.5.0. Bug stays open until this is somehow fixed.

1.5 is fully supported with commit e9c60af75ff686a2cf36ab9e51f31e06d765a4ea.
