Ink splashes should start at the touch point

Ink splashes should start at the touch point

Previously, they always started at the center of the RenderInkWell. Now we
remember the local coordinates we computed during the hit test and provide that
information when handling the event.

File sky/sdk/lib/framework/rendering/object.dart (right):

https://codereview.chromium.org/1180553002/diff/20001/sky/sdk/lib/framework/r...
sky/sdk/lib/framework/rendering/object.dart:256: class HitTestData {
HitTestEntry

and rename all the variables that refer to it as "data" to "entry".

https://codereview.chromium.org/1180553002/diff/20001/sky/sdk/lib/framework/r...
sky/sdk/lib/framework/rendering/object.dart:257: final RenderObject entry;
Rename this to "target".

https://codereview.chromium.org/1180553002/diff/20001/sky/sdk/lib/framework/r...
sky/sdk/lib/framework/rendering/object.dart:260: }
Constructor first, then fields.
Also, make the constructor const. Not that it really matters since RenderObjects
can't be const, but...

https://codereview.chromium.org/1180553002/diff/20001/sky/sdk/lib/framework/r...
sky/sdk/lib/framework/rendering/object.dart:265: RenderObject get result =>
path.first.entry;
If we don't use this, drop it.
If we do, maybe rename it "finalTarget" or something?
