WPF - WritableBitmapRenderHandler Avoid null bitmap references upon wakeup. (#4619)

awbushnell · web-flow · commit cbc89802ef63 · 2023-11-01T06:14:36.000+10:00
Force initial bitmap creation upon wakeup when the image.source is null... Happens if sizing etc. rapidly and the UI thread short circuits when CreateNewBitMap is true and the first wake up occurs with it 'false' amd image.Source is still null...
