* Discard dotfiles when looking for fonts
So as not to pickup, among other things:
* macOS resource forks
* *nix hidden files (which may be stale fuse ghosts on Kindle)
* Update Kindle font blacklist
Up to FW 5.9.6
Basically blacklist anything non-LGC, requiring lab126's FT build, or FC tweaks.
One day we'll fix CRe instead, maybe.
* Minor cleanup
We don't ship Droid Sans Fallback anymore
* Tweak UI fallback font list for better coverage
* Bump base & fonts
To pickup related changes
It turns out that one of our mupdf patch reads the FONTDIR env var
and uses it in a totally different way so we will use another env var
EXT_FONT_DIR to define external font directory for different platforms.
to support custom font directory for EPUB documents
Now Koreader could find fonts in the "fonts" directory in the USB root
directory of kindle, Kobo and PocketBook devices, thus no need to copy
fonts to "koreader/fonts" directory.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
