Remove bm_orig (#367)

* Remove bm_orig

* Fill image_data and image_type automatically when Bitmap is provided
* Generate bm_display out of the image_data vector
* Convert directly when user switches between PNG and JPEG format
* Make BitmapScale() not use bm_orig
* Only place PNG image in clipboard

* Pass vector by reference

* Rename Vector to Buffer in function names

* Remove wxBitmap from Image constructor and move functions to System

This commit modifies the code blocks calling the Image constructor so that
the image data vector is always passed.

* Use wxImage Rescale operation to rescale image in-place

This commit makes the code avoid an additional back-and-forth conversion
from and to wxBitmap.

* More precise function names for helper functions

The conversion is to and from wx{Bitmap, Image} and should not be
confused with Image. Thus precise the function names.

* Increase code readibility

Values are fixed for PNG file format

Remove obsolete function MakeInternallyScaled() (#366)

As wxWidgets handles the correct drawing depending on the set DPI
by using device-independent pixels, the function MakeInternallyScaled()
becomes obsolete. This commit removes the function.

Use device-independent pixels in MyFrame (#364)

Use the device-independent pixels to abstract away the problems of
scaling on displays with different DPI. wxWidgets will handle the
correct scaling.

Please refer to <https://docs.wxwidgets.org/3.2/overview_high_dpi.html>
for more details about High DPI support in wxWidgets.

This targets mainly the toolbar that shall display correctly
on High DPI displays.
