pose.Translation().X() and pose.Translation.Y() are common operations,
so shortening them to pose.X() and pose.Y() would be convenient.
Java uses the getX() convention so that is used instead of X() for Java.
We already have predefined linear acceleration units and angular
velocity units. This makes defining acceleration constraints for angular
trapezoid profiles more convenient.
No tests were added for this because the base unit conversions are
already tested. Angular acceleration just adds another time dimension.
With the new extraction method, we would need to provide an opencv. However, all of our tools that use opencv use an alternate version of OpenCV, so that would interfere.
This adds an artifact where opencv is statically linked into cscore, but wpiutil is a shared dependency. This solves some shared state hacks, and the extraction works so much better, so its worth making this change to allow that
Also move some things in HAL for consistency.
WAS:
C++:
- C APIs: #include "mockdata/AccelerometerData.h"
- User side class: #include "simulation/AccelerometerSim.h"
Java:
- JNI APIs: hal.sim.mockdata.AccelerometerData (and a few classes in hal.sim)
- User side classes: hal.sim.AccelerometerSim
IS:
C++:
- C APIs: #include "hal/simulation/AccelerometerData.h"
- C++ class: #include "frc/simulation/AccelerometerSim.h"
Java:
- JNI APIs: hal.simulation.AccelerometerData
- User side class: wpilibj.simulation.AccelerometerSim
* Add new combined native class loader
Allows us to extract a list of binaries that depend on each other, and load them successfully
It is correct that there is no implementation in wpiutil for the new native method. That is a requirement, because its needed to load the libraries, and we cant load the wpiutiljni native library since it depends on wpiutil. Instead we have a separate library built with the tools plugin that handles everything
Previously this would list ALL /dev/video* devices. In recent versions of
Linux this leads to listing duplicate devices, as many USB cameras provide
both a video device and a metadata device, and only the video device can
actually be used for streaming.
The most common mistake users (including contributors to WPILib) seem to make while creating new constraints is ignoring some sort of edge case that causes the calculated minimum acceleration to be greater than the calculated maximum acceleration.
This specialized exception, with its detailed error message, should make it easier and quicker for said users to debug and fix bugs within their constraints.

If the 64 bit FPGA timer rolls over, a 32 bit value is added for
the rollover, an artifact of when it was a 32 bit timer.
The 64 bit microsecond timer won't rollover for 500k years so remove the
check for simplicity.
Fixes#2504
Valgrind caught this one. If you default initialize a Trajectory, it
doesn't initialize m_totalTime. This means a subsequent call to
Trajectory::TotalTime() returns the value of an uninitialized variable.
3512's software was using 0_s as a sentinel value for when a trajectory
was empty. We didn't notice a problem before because Linux zero-inits
memory.
