vcl's DrawBitmap methods have a very nice optimisation, that reduce
the blit to exactly the area covered (i.e. taking into account clip,
scale etc.). This was hand-coded, now moved out to own AdjustTwoRect
method, and also used from DrawOutDev / CopyArea.

No classes derived from this and they are not virtual methods.

In general it's good to have file opening in just one place. In
particular, this means SvFileStream can now open files located in the
app package (.apk Zip archive) on Android, we don't need to unpack
them into separate files.

Having SvFileStream call the file opening etc functions here, instead
of calling open() directly itself, means we won't have to duplicate
the Android .apk hooks there, too.

decompose() would return incorrect rotation angle and scales when the
angle was exactly 180 degrees, due to FPU rounding error.  This commit
fixes it.

This problem would manifest itself when inserting an image into
Calc/Draw, cropping it, and flipping it vertically or rotating it
at exactly 180 degrees.  Before the fix the image would simply disappear.
