  1. Safeguard against very large Bitmap creation (#2662) 

    * Safeguard against very large Bitmap creation

Because we rely on the transform `Matrix` returned from the `Canvas` to size a `Bitmap` when using software rendering, an erroneous matrix value can cause a very large Bitmap to be allocated, triggering an OutOfMemory exception.

We've encountered such a situation when using `layoutlib` for screenshot tests, which uses a `NopCanvas` [on initial render](https://cs.android.com/android/_/android/platform/frameworks/layoutlib/+/7b05b277beee599532606e9bb6d7a71f5ca2ab6e:bridge/src/com/android/layoutlib/bridge/impl/RenderSessionImpl.java;l=543;bpv=1;bpt=0;drc=085857f145aac790e2a08cf6eb9546f98e26c338) that can return an invalid `Matrix.

* Use a hardcoded upper bound and add additional checks
