always optimize bitmap transform to translate+scale if possible (tdf#138068)
Commit 828504974d70111e make OutputDevice::DrawTransformedBitmapEx()
always call DrawTransformBitmapExDirect() in preference to explicitly
converting to DrawBitmapEx() if the transformation wanted was at most
translate+scale, in the hopes that these days the backend implementations
work well enough. But it turns out only the Skia backend handles that
without loss of performance. So always do the conversion to DrawBitmapEx()
if possible. It's so simple that it possibly makes sense to always do
this, regardless of the backend.
