* Fix typo for POINTING_DEVICE_GESTURES_SCROLL_ENABLE
Follow the name written in documentation which follows
POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE
* Reword the blurb about POINTING_DEVICE_GESTURES_CURSOR_GLIDE_ENABLE in docs
Static x & y should be the same type as touchData.xValue &
touchData.yValue: uint16_t.
Their delta could be larger than int8_t and should be constrained to
mouse_xy_report_t.
* avr i2c_master: Fix 1ms timeout
i2c_start() produces a minimum time_slice of 1ms for use as timeout
value.
The timer granularity is 1ms, it is entirely possible for timer_count
to tick up immediately after the last timer read and falsely trigger
timeout with a '>= 1' comparison.
* avr/drivers/i2c_master: Use timer_elapsed()
