* Changed SVG output so all coordinates are to 1 decimal place. Adjusted tests accordingly. * Checking test1 SVGs via hashcode. * Added testing of all generated test files by comparing hash-codes. The few cases where this doesn't work are mentioned in the code. * close streams * Close files after writing - Windows won't delete them otherwise. * Changes post-review. * Proposed change post-review for further discussion. * Use MolDraw2D_details::doubleFormat. * Copied improved check_file_hash() from catch_tests.cpp. Updated a few hash codes. * Copied improved check_file_hash() from catch_tests.cpp. Updated a few hash codes. Added hash codes for no-Freetype version. Co-authored-by: David Cosgrove <david@cozchemix.co.uk> Co-authored-by: Greg Landrum <greg.landrum@gmail.com>
