in order to have debugging facilities in framebuffer:init(), we hand
over the debug function as soon as we can.
Also, set a viewport for Kobo Mini. Hopefully, it fits most people -
I can only test on my unit.
This allows for Viewport debugging. It is configured via an environment
variable, EMULATE_READER_VIEWPORT. It works with Lua table syntax, e.g.:
EMULATE_READER_VIEWPORT="{x=10,w=550,y=5,h=790}"
the height of filechooser is provided when creating filechooser
widget since there may be no title as in filemanger which needs
a special title widget to contain filemanger menu.
Since the new Screen:getSize modthod returns a regular table
instead of a Geom which is set to the dimen field of readerview,
there is no copy method in the dimen field. And we don't need to
copy dimen any more since the result won't be modified. Even the
screen page area somehow needs to be modified, the caller of this
function should make a copy of that variable by itself.
Events have been passed to the frontend/device (or /input) code before.
Some of them have been handled in the FFI/input code, however. That
seems to be highly critical with regard to timing, though, so we just
let it enqueue the event for our code to process later. That way, a
mutex that locks the input event queue can be freed faster.
Lots of the device-related distinction wandered into
base/ffi/framebuffer_<driver>. This eases the refresh logic in
UI manager, which basically only decides what kind of refresh
to trigger. The device specific configuration in the framebuffer
driver decides how to realize that whish.
screen.lua is gone, in its place is now the framebuffer driver.
The device abstraction decides what framebuffer driver to load.
While looking into #1219 I accidentally ended up refactoring some stuff.
Tested in emulator and on H2O, but be wary because I might have overlooked something.
Don't increase counter for regional updates
Also some workarounds for Kobos
Try to avoid update_regions_func poisoning
Reset it at the end of repaint() even if nothing was found dirty
Ensure regional updates are always PARTIAL, in
case we get a region attached to an automatically triggered refresh, not
marked force_partial [which, hey, shouldn't happen, but apparently does
sometimes ^^]
