Summary:
This change aims to reduce the number of bitmap pools by definiting a default pool which can contain bitmaps of different sizes.
A side benefit is that this single pool facilitates handling the case where a view gets resized too.
So overall, this should be both more generic and efficient compared to the previous approach.
