files. Because of this, the generated cairo-test-constructor only
contained a few tests and the test suite was thus incomplete.

Some tests hand-code ARRAY_LENGTH(). It is now provided by
cairo-test.h, so it can be reused.

Avoid calling libtool to link every single test case, by building just one
binary from all the sources.
This binary is then given the task of choosing tests to run (based on user
selection and individual test requirement), forking each test into its own
process and accumulating the results.

In order to run under memfault, the framework is first extended to handle
running concurrent tests - i.e. multi-threading. (Not that this is a
requirement for memfault, instead it shares a common goal of storing
per-test data). To that end all the global data is moved into a per-test
context and the targets are adjusted to avoid overlap on shared, global
resources (such as output files and frame buffers). In order to preserve
the simplicity of the standard draw routines, the context is not passed
explicitly as a parameter to the routines, but is instead attached to the
cairo_t via the user_data.
For the masochist, to enable the tests to be run across multiple threads
simply set the environment variable CAIRO_TEST_NUM_THREADS to the desired
number.
In the long run, we can hope the need for memfault (runtime testing of
error paths) will be mitigated by static analysis. A promising candidate
for this task would appear to be http://hal.cs.berkeley.edu/cil/.

Parts of the stroker depend upon whether we have in effect a reflection
matrix (one whose determinant < 0). This test incopororates the same
drawing under the a couple of reflections to exercise stroking under
matrices with both positive and negative determinants.
