tdf#121778: Work around odd macOS 10.14 graphicsContextWithWindow failuredistro/collabora/lov-6.1
Although Stephan's original commit message below talks mainly about a unit test, this change helps at least in tdf#121778, too, and possibly other cases. It is interesting that wihout this change, a lot of these warnings are printed before the crash: warn:vcl.quartz:42670:52899343:vcl/quartz/salvd.cxx:312: No context Original commit message: When running on macOS 10.14, both master and libreoffice-6-1 (at least) started to fail CppunitTest_vcl_bitmap_render_test with > /Users/stephan/Software/lo2/core/vcl/qa/cppunit/bitmaprender/BitmapRenderTest.cxx:90: Assertion > Test name: BitmapRenderTest::testTdf113918 > equality assertion failed > - Expected: mcBlueOrIndex: 255, mcGreen: 255, mcRed: 255, mcAlpha: 0 > - Actual : mcBlueOrIndex: 1, mcGreen: 112, mcRed: 15, mcAlpha: 0 in --enable-debug/--enable-dbgutil builds. I tracked that down to the OSL_DEBUG_LEVEL>0--only call to Scheduler::ProcessEventsToIdle in test::BootstrapFixture::setUp (test/source/bootstrapfixture.cxx). If that call is also included in non-debug (i.e., OSL_DEBUG_LEVEL=0) builds, or if it is removed from all builds and instead an unsuspecting [NSApp nextEventMatchingMask: 0 untilDate: nil inMode: NSDefaultRunLoopMode dequeue: NO]; is added directly before the call to pVDev->SetOutputSizePixel(Size(2480, 3508)); at the start of BitmapRenderTest::testTdf113918 (vcl/qa/cppunit/bitmaprender/BitmapRenderTest.cxx:76), the test always fails. What happens is that, after such a nextEventMatchingMask call done, the call to NSGraphicsContext graphicsContextWithWindow in AquaSalVirtualDevice::SetSize (as called from the SetOutputSizePixel call in the test) returns nil, for unclear reasons. Until those underlying reasons are understood, change the code of SetSize to "fall back to a bitmap context" also in case the graphicsContextWithWindow call returned nil.
