This page uses JavaScript to parse test log files and create the
test table according to the results. It also allows dynamic selection
and hiding of rows/columns based on a chosen parameter and table
structure change, by dragging a field from rows to columns and vice
versa.
Left click selects the cells with the chosen parameter-value association.
If these cells are exactly the only show cells, it hides them and shows
all the other ones, instead.
Right click inverts the visibility of the cells with the chosen
parameter-value association.
When some rows are hidden, the PASS/NEW/FAIL/XFAIL/CRASH counters show
both the currently shown test case count and the total count, if they are
different: "23[62]" means that there are 62 test case in that category,
but only 23 are currently visible.
Dragging a field from the row (or column) header to the column (or row)
header rebuilds the table to have that field along the columns (or rows),
updating PASS/NEW/FAIL/... counters and showing the whole table again.
Test names are hyperlinks to the test log.
Images are hyperlinks to themselves.
Make linear-gradient-large ref image match xlib gradients (both on nvidia
and on macosx) and pixman gradients (when patched to compute the linear
gradients using floating point math).
Degenerate linear patterns are considered clear if they have
EXTEND_NONE, the average of the first and the last stop if they are
EXTEND_PAD, the weighted average of the stops (based on the size of
the interpolation range in which they are active, just like integrating
over the whole interpolation range and taking the average) if they are
EXTEND_REPEAT or EXTEND_REFLECT.

Merge clip-*-unbounded tests and add self-intersections to the paths
that are drawn. This exposes a bug in the unbounded fixup code in quartz.

To be consistent with _cairo_gstate_clip_extents, the context's clip
should be intersected with the target surface extents (instead of only
using them when there is no clip).

If the gstate clip in _cairo_gstate_int_clip_extents() has all_clipped
set (and path NULL), then it returns the gstate target extents instead of
an empty rectangle. If the target is infinite, then it says the clip is
unbounded.

Use two levels of pthread support: a minimal level used to
build cairo itself, and a full level to build threaded apps
which want to use cairo. The minimal level tries to use
pthread stubs from libc if possible, but falls back to the
full level if that's not possible. We use CFLAGS=-D_REENTRANT
LIBS=-lpthread to find a real pthread library since that seems
to work on every unix-like test box we can get our hands on.
In that check, we call functions that require a specific surface type
with surfaces of a different type and check that they don't crash and
set the correct error.
In particular, it checks that finished and surfaces in an error state do
not do bad things, like cause crashes.
So far this test only checks surface APIs, but it should be extended to
cover all APIs.
Please update this test when new APIs get added.

How did that get there? I obviously ran the test to generate the output,
so where did it spring as it is the old version of the function?
From 16364768d7.
Mysteries will never cease.
