[OpenJDK 2D-Dev] RFR: 8242004: TextLayout throws Exception with a non-invertible transform

[Philip Race]

bug: https://bugs.openjdk.java.net/browse/JDK-8242004
webrev: https://bugs.openjdk.java.net/browse/JDK-8242004

Several code paths can end up in the method shown in the bug report
with a non-invertible transform.

As much as possible, we can prevent them reaching here by checking in 
the rendering code.

If we do get here, which should now be possible only when directly creating
a TextLayout, we can use a default TX. Subsequent rendering of the 
TextLayout
will be handled by the other checks being added.

A regression test is provided which checks various APIs to make sure no
exception is thrown.
