Ensures that all files that Git considers to be text will have
normalized (LF) line endings in the repository. When core.eol is set to
native (which is the default), Git will convert the line endings of
normalized files in your working directory back to your platform's
native line ending.

Commit 9e78a41 declared isinf() as std::isinf(), because isinf() was not
declared on Ubuntu 16.04. But now the builds fail on Ubuntu <= 15.10,
because isinf() is declared there:
effects/Contrast.cpp:61:12: error: ‘constexpr bool std::isinf(double)’ conflicts with a previous declaration
using std::isinf;

Thus use std::isinf() directly instead of declaring isinf() as
std::isinf().
* scrubbing:
Allow scrub timer interval to be 1 ms, without bogus out-of-memory warnings.
Less scrub lag: avoid redundant disk traffic in Mixer...
Less scrub lag: don't poll for available data, get woken up directly
Fix for this bug: If the cursor/selection start is moved using the keyboard, then
audio position shows the previous cursor/selection start.
Simple fix in void AudacityProject::TP_DisplaySelection(). The play region is now updated
before its start is used for audio position.
Fixes the following bug: if the zoom level is such that the jump does not cause a visible
change in display of the tracks, then the selection in the selection bar, and the play
region are not updated.
The fix simply moves the location of the call to TP_DisplaySelection(), so that it is called
irrespective of whether the tracks are redrawn.
isnan() is not defined when compiling with g++ 5.3.1 on Ubuntu 16.04. It
is called std::isnan() in C++11 instead. Therefore use wxIsNaN() instead
which already defines the correct name.
... Start scrub by click or double click on the scrub head; release button or
not; then move.
If you release before moving, you get scrubbing as before, controlled by
motion. Click or drag to switch in and out of seeking. Stop with ESC,
spacebar, etc. No change of selection.
But now if you drag, then scrubbing contines until you release the mouse or
otherwise stop with a key.
If by release of the mouse, then the selection changes as if by a click at
the last play position. If you hold shift, then, as if by shift-click.
If drag begins with a double-click, then the play head remains centered and
the track moves.
... The main rule seems to be, during the repainting of one window, don't draw
onto any other DC for that or any other window. Don't refresh any other window.
