Break the non-PCB-specfic parts of PCB_REFERENCE_IMAGE out
to a common REFERENCE_IMAGE class, which is then composed into
the PCB_REFERENCE_IMAGE. This will make it easier to bring the
transform origin logic to eeschema without repetition.
This has always been possible (especially through the properties
panel with large scales), but it's even easier if the transform
origin is near a manipulated corner.
Check and reject scales that result in an overflowed image box.
This is stored as an offset from the image position,
which is the centre of the image. When interactively edited, the
transform origin stays in place. This makes it easier to scale an image
around some fixed feature in the image.
For now this is not saved out to the format, so it
reinitialises to (0, 0) each time. This means scale around
the midpoint, which is the current behaviour.
There was a gentle mish-mash of booleans, some with
true being left/right and some up/down, and some functions that
can flip in both axes (which is never actually done, and doesn't
really make geometric sense).
Replace all this with the FLIP_DIRECTION enum class, which makes
the intention completely unambiguous.
This also then allows a small scattering of simplifications,
because everything takes the same type and you don't have to
fiddle booleans to fit.
- Keep original image data. When loading JPEG, this avoid recompression
that changes file data and decreases image quality
- Allow schematic and page layout editors to store non-PNG data as well
- Move page layout editor to store base64 instead of hex-coded data
in GetMsgPanelInfo() (PPI, scale).
m_image name was confusing: it is not a wxImage, but a BITMAP_BASE item,
and m_image name was already in use in BITMAP_BASE, used inside SCH_IMAGE.
Bitmap properties dialog: show PPI value and add Title to dialog.
Fixes rotating bitmaps with "rotate counterclockwise",
"rotate clockwise" and "move exactly" commands.
Only rotation by 0, 90, 180 and 270 degrees is supported
for bitmaps. Other values are rounded to the nearest 90
degree multiple.
There is a different bug that this commit doesn't address,
which is that BITMAP_BASE::Rotate() got its CW/CCW logic
reversed ("m_image->Rotate( false )" should rotate CW, but
does not).

We report bitmaps as being 'on' a copper layer because they are
associated with it but they are not actually physical parts so should
not be included in the DRC checks
Additionally, Bitmaps effective shape starts are the top left corner
rather than the center (unclear why that was there in the first place)

Also adds some debugging to try to catch dangling pointers.
Also adds a cache for group bounding boxes (which will be expensive
to calculate for large groups).
