When using wxBitmap ctor taking wxDC, the bitmap should inherit the
scale factor of the DC, both because it's already the case in the other
ports and because it makes sense to do it.
Add a unit test checking that this is the case in all ports now.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
