Tag version 0.6.4-beta

When a selection box is dragged, holding Ctrl while pressing the arrow
keys will shift the mosaics one sixel at a time.

If a shifting sixel encounters a non-mosaic cell it will pass through to
the other side of it.

 ## Building
 ### Linux
-Install the QtCore, QtGui and QtWidgets libraries and build headers, along with the qmake tool. Depending on how qmake is installed, type `qmake && make -j3` or `qmake5 && make -j3` in a terminal to build, you can replace -j3 with the number of processor cores used for the compile process.

 The above should place the qteletextmaker executable in the same directory as the source, type `./qteletextmaker` in the terminal to launch. Some Qt installs may place the executable into a "release" directory.

 The following X/26 enhancement triplets are not rendered by the editor, although the list is fully aware of them.
 - Invocation of Objects from POP and GPOP pages.
 - DRCS characters.
-- Modified G0 and G2 character set designation using X/26 triplets with mode 01000.

 By checking "raw values" it is also possible to view and edit the raw Address, Mode and Data numbers of the triplets. When editing triplets this way, remember that address values 0-39 select a column triplet which has one set of modes and address values 40-63 select a row triplet which has a different set of modes.

 ### Setting the Active Position
 The Active Position, whether set explicitly by a "Set Active Position" triplet or by a row or column triplet, can only be moved in screen address order i.e. from left to right within a row and then from top to bottom across rows. In other words:
