Vadim Zeitlin 171f9ab8f4 Make wxBitmap::HasAlpha() and UseAlpha() available in all ports ... HasAlpha() was already available in most of them, now ensure that it's present in all of them, especially as it has a reasonable default implementation. UseAlpha() was only present in wxMSW and wxOSX and still remains only implemented there, but provide at least a stub for it elsewhere as well to avoid problems such as that of #17393. See #22545. Closes #17397.		2022-06-20 00:38:09 +02:00
