According to the Vision API docs, each response block has a set of related
vertices, like the following:
{
"description": "ABBEY",
"boundingPoly": {
"vertices": [
{
"x": 45,
"y": 50
},
{
"x": 181,
"y": 43
},
{
"x": 183,
"y": 80
},
{
"x": 47,
"y": 87
}
]
}
},
You'll need to capture the point that the user clicks and cycle through
each block to see whether the point is within the block's boundaries.
