+// This a setting that should be set manually and it affects LO
+// code rather than Skia itself. It basically controls setting
+// BackendCapabilities::mbSupportsBitmap32.
+// Since Skia does not natively support 24bpp, the preferred setup is
+// that the setting should be enabled, it makes the code faster and cleaner.
+// Unfortunately VCL historically splits alpha into a whole separate
+// bitmap and works with 24bpp+8bpp, which is generally more complicated,
+// more error-prone and just worse, but that's how LO code has been
+// written and so there are many places in LO that expect this and
+// do not work correctly with true 32bpp bitmaps.
+// So ultimately the 24+8 split should be dumped (preferably in all of LO,
+// not just the Skia-related code), but until all of LO works correctly
+// with 32bpp disabling this will avoid such breakages.
