This adds more documentation about the viewport offset calculations
for refreshing rotated viewports.
The old behaviour also was (still) buggy, even after the latest round
of fixes. Now, the offsets when rotated are hopefully calculated correct.
The calculation did not correctly calculate the offset in rotated
modes when the rotation was 90 or 270 degrees. Under these circumstances,
getWidth() and getHeight() did return rotated values for the framebuffer,
while Device.viewport did return not rotated values.
WIP, untested, can probably simplified some more.
Good news is, it should be smarter, and thus provide a smoother user
experience :).
Relies on the relevant changes in base.
FIXME!
Needs actual confirmation from people with the HW!!
Once that's done, some device checks will probably need to be
udated in the codebase to take those new devices into account ;).
This should fix#1016.
Usage for #1016:
Create a file named "custom.event.map.lua" in the koreader directory
with the following content:
return {
[102] = "LPgFwd",
}
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.
