Without this, the drawing avoids the fast path just because the position has an offset, even though it normally works. It seems this should be enabled by default, but it isn't.

// Unfortunately VCL historically splits alpha into a whole separate

// 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.
