Revert "take rotation into account when calculating display size"

This reverts commit 0aabb155d351656bbb804619279dd497b06c48b0.

Fixing xinput_do_set_prop into cleaner xinput_do_set_int_prop Also fixing property issue on invert axes

remove invertX/Y from evdev config outputting

invertX/Y is automatically handled by xf86ScaleAxis
avoid outputting it so users don't manually change it
(it is still set/unset in dynamic calibration when needed though)

CalibratorEvdev: remove TODO about evdev 2.3.2

we now support (and have tests) for evdev 2.7.0

Merge branch 'evdev_inversion'

At last! See patches for details, tester for tests.

Fix evdev calibration when invertX/Y is set

From evdev 2.3.2 onwards, it does something crazy when the
invertX/Y option is manually set
This has to be undone in the calibrator before doing the calib
calculation.

I say 'manually set' above because invertX/Y is a useless option:
xf86ScaleAxis can deal with axis inversion automatically,
hence, nobody should ever ever set invertX/Y ever.
Just let the calibrator calculate the calibration for you!

Copy Calibrator::finish() literally to CalibratorEvdev::finish()

Merge branch 'calibration_cleanup'

Cleanup/rewrite of calibration code, equivalent calculations (checked
with tester); actually, slightly more accurate calculations.

Rewrite and simplify swapping

Inspired by forest bond's 'calibrator: Convert to device coordinates
immediately.' patch:
https://github.com/forest-bond/xinput_calibrator/commit/12832527fba6dd1b3135751257ca6a734aa571cd

two minor API cleanups

calib calculation: rewrite and document transformation to 'raw' values

calib: make our scaleAxis function use floats to avoid rounding errors

calib calculation: rewrite and document num_block scaling

calib calculation: use floats

calib calculation: move min/max correction before transformation

calib calculation: calculate average of clicks first

calibrator: in finish code, correct new_axys to new_axis (no code change)

Merge branch 'evdev_emulation_interface'

Evdev 2.7.0 tester

It shows that the evdev regression is in the use of the invert_x/invert_y option, together with axis swapping (which is silly, because invert_x/invert_y are options you don't manually need to specify because of the mathematical properties of xf86ScaleAxis)

Tester: run standard tester and evdev tester

EvdevTester with evdev 2.7.0 emulation code

Create CalibratorTesterInterface

Merge pull request #38 from Tokoyami/master

Take rotation into account when calculating display size

take rotation into account when calculating display size

changed GuiCalibratorX11::redraw() to fall back to X if xrandr is not available

Merge branch 'tester'

A tester object to faithfully test the calibration routines.
This will be reused for testing the evdev calibration (which
is non-standard) as well.

Some more tests, kind-of

show maxdiff during testing

Different old_axis orientations and parameters

driver emulation implementation

Add (xf86)scaleAxis code

Tester: test calibration routines and make assumptions explicit

The tester will serve to test the calibration code,
while doing so, it will make the assumptions about the calibration
in the driver (e.g. how it uses the calibration values, and
especially swap_xy and inversion and the like) explicit.

The goal is to give assurances about the correctness of the calibration,
without needing to have devices in all possible swapaxes/inversion
combinations.
