Stylus fusion: Use SOURCE_BLUETOOTH_STYLUS dynamically for events
Previously, whenever an external stylus was connected, the source for
all touch devices (touchscreens, styluses, drawing tablets, etc.) would
change to include SOURCE_BLUETOOTH_STYLUS. This meant that all events
produced by these devices would also include SOURCE_BLUETOOTH_STYLUS,
even if the event was unaltered by stylus fusion.
In this CL, we introduce a way to dynamically add
SOURCE_BLUETOOTH_STYLUS to event streams that are a product of stylus
fusion.
The problem we are trying to solve is to be able to differentiate a
normal event stream from a stylus vs. an event stream from a stylus or
touchscreen that has additional information fused from a bluetooth
device. Previously, both such streams would have
SOURCE_BLUETOOTH_STYLUS, whereas now, only the latter case would use
that source.
