Remove gyro compensation filter
Merge branch 'simple_gyro_comp' of github.com:DrTon/Flow
merged DrTon/simple_gyro_comp that removes the somewhat arbitrary compensation filter and added clamping to the compensated pixel flow. It is equal to the maximum possible pixel range that is computed by the sensor. Added a new read-only parameter (BFLOW_MAX_PIX) that contains the flow search window-size (currently +/- 4)
Merge pull request #9 from PX4/compensation_fixes
