Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Include pyversion.mk include the protected part of the buildlink3.mk
files, not over and over again.

Update to 1.8.2:

Overview of changes from pycairo 1.8.0 to pycairo 1.8.2
=======================================================

Pycairo 1.8.0 resulted in crashes for some applications using threads. So
upgrading to 1.8.2 is recommended for threaded applications.

Bug Fixes: #19287: Threading support results in crashes in cairo.ImageSurface

New Methods:
    Context.set_scaled_font

API Changes:
    Matrix multiplication:
    old code: matrix3 = matrix1 * matrix2
    new equivalent code: matrix3 = matrix1.multiply(matrix2)
    matrix3 = matrix1 * matrix2
    is now equivalent to matrix3 = matrix2.multiply(matrix1)
    which is consistent with standard matrix multiplication.

Log message:
Fix cairo DEPENDS.

Log message:
Update to 1.8.0:

Overview of changes from pycairo 1.6.4 to pycairo 1.8.0
=======================================================
General Changes:
    Pycairo 1.8.0 requires cairo 1.8.0 (or later).
    Add documentation (available separately)

Bug Fixes:
    18101: Add support for threading
    18947: cairo.SurfacePattern should INCREF the used surface

New Methods:
    ScaledFont.get_scale_matrix
    Surface.mark_dirty_rectangle
    Surface.set_fallback_resolution

New Constants:
    cairo.EXTEND_PAD
    cairo.HAS_IMAGE_SURFACE
    cairo.HAS_USER_FONT

API Changes:
    Surface.mark_dirty: no longer accepts keyword arguments with default
    values.
    PycairoPattern_FromPattern (C API): has a new 'base' argument - to fix
    #18947.

Other Changes:
    Allow unknown cairo Pattern/Surface types to use the pycairo base
    Pattern/Surface type.

Log message:
make this work with python-2.4 again

Log message:
Update to 1.6.4:

Overview of changes from pycairo 1.4.0 to pycairo 1.6.4
========================================================
General changes:
    Pycairo 1.6.4 requires cairo 1.6.4 (or later).
                  requires Python 2.5 (or later).

Bug fixes:
    16112: Fix win32 'python setup.py ...' build -- use double quotes

New Methods:
    Context.has_current_point
    Context.path_extents
    ImageSurface.format_stride_for_width
    PSSurface.get_eps
    PSSurface.set_eps
    PSSurface.ps_level_to_string
    PSSurface.restrict_to_level
    Surface.copy_page
    Surface.show_page

New Constants:
    cairo.PS_LEVEL_2, cairo.PS_LEVEL_3

Other changes:
    test/pygame-test1.py, test/pygame-test2.py : pygame tests

    examples/cairo_snippets/snippets/ellipse.py : Update
    so line-width is a constant width in device-space not user-space

Log message:
PYTHON_VERSIONS_ACCEPTED+=25

Log message:
update to 1.4.12
changes:
-minor build framework fixes
-allow cairo.Context to be subclassed
