bc7bc29740 Added HDF5 file to demonstrate dynamically plotting a subset of a very large dataset
* Loads only data that is currently visible
 * Downsamples to avoid plotting too many samples
 * Loads data in chunks to limit memory usage during downsampling

6ae0892ea0 Set version strings to 0.9.8 in source; these will be updated with major releases.
Added tools/setVersion script
setup.py now auto-generates version string based on pyqtgraph/__init__ and git info, if available

f136b33033 Profilers controllable via PYQTGRAPHPROFILE.
A new function profiling system is implemented.  Most importantly, this
allows one to profile various internal functions directly by setting the
`PYQTGRAPHPROFILE` environment variable to a comma separated list of
function and method names, e.g.

    PYQTGRAPHPROFILE=functions.makeARGB,ImageItem.render \
        python -mexamples

Specifically, items in `PYQTGRAPHPROFILE` must be of the form
`classname.methodname` or `dotted_module_name.functionname`, with the
initial "pyqtgraph." stripped from the dotted module name.

Moreover, the overhead of inactive profilers has been kept minimal: an
introspective check of the caller's name (only if `PYQTGRAPHPROFILE` is
set) and a trivial function (not method) call per profiler call.

The new profilers rely on `sys._getframe` to find the caller's name,
although the previous system (passing the caller's name explicitely)
could certainly have been kept instead.

Finally the API of profilers has been changed: register a
profiling point simply by calling the profiler, and profilers are
automatically flushed on garbage collection.  See the docstring of
`pyqtgraph.debug.Profiler` for more details.

23a0d6d7c0 Use actions of ViewBox's contextMenu in full menu.
The main change is on `ViewBox.getContextMenus`, which now returns an
up-to-date of actions that `GraphicsScene.addParentContextMenus` can use.

Also, `getContextMenus` was given a default implementation in the base
class (falling back on `getMenu` if defined), and some cleanup was done.

2e61be739f Don't copy the context menu of ViewBoxes.
This allows customization of the context menu of a ViewBox simply by
calling viewbox.menu.addAction(...).  See issue #13.  Also some cleanup.

dac7eb5817 Faster import of PyQtGraph.
* RawImageWidget (and thus OpenGL) isn't imported by default anymore.
* scipy.stats.scoreatpercentile is replaced by numpy.percentile.

This commit has not been tested as the example runner is currently
broken.

58ed8ee7bd ViewBox overhaul. Cleaned up code pathway:
- setRange now only affects target range
  - updateViewRange only affects view range
  - updateMatrix only affects childGroup transform
  - updateMatrix is only called before a render

Pathway now looks like:
        setRange -> updateViewRange -> matrix dirty -> ...
                                    -> sigRangeChanged

        ... -> prepareForPaint -> updateAutoRange, updateMatrix if dirty

96a4ff7cd5 Fixes:

5ef8b1d01a Merge branch 'axis_fix' into develop
Fixed improper tick spacing and axis scaling
    This requires an API change:
     - AxisItem.setScale(float) has the usual behavior
     - AxisItem.setScale(None) is deprecated (but still works). Instead use:
     - AxisItem.enableAutoSIPrefix(bool) to enable/disable SI prefix scaling
    Also makes the API more intuitive since these features are now accessed and implemented independently.

fixes #4
