Android: Avoid calling dw_main_sleep() and dw_main_iteration() during expose
callbacks. Expose callbacks are the only ones that run on the UI thread...
due to Android implementation restrictions. Therefore calling any blocking
functions such as dw_mutex_lock() will cause a message loop to be run, via
dw_main_sleep() or dw_main_iteration(), these use hacky stuctured exception
handling methods to return on Android, so to be safe avoid it completely.
Call dw_mutex_trylock() instead, and if it can't lock the mutex... call
dw_render_redraw() to trigger a new expose event.
