Explicitly use OSX
Previously this was inherited via PBD.

On MacOS/X,  this adds
  "-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags

Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")

On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.

Return of image-surface backed canvas (windows graphics performance)
This partially reverts 2edbda2526.

Using cairo-groups increases performance on MacOS, and retains
retina-resolution.
However it adds a performance regression for MS Windows graphics
rendering. cairo-groups use a "similar" surface, not an image surface.
Empirically this adds significant overhead compared to rendering
using the CPU and using bitblt.

Replace explicit image-surface with cairo pattern/group
For MacOS/X this is equivalent, rendering happens using a
CGBitmapContext + image-surface. Windows and Linux needs profiling
for respective equivalent surfaces.

Allow for per-widget image-surface backing
This is an intermediate commit, before replacing image surfaces with
cairo pattern groups.

The eventual goal is to reduce flickering and/or use
CPU + bitblt for specific widgets instead of cairo
graphics-cards accel.

This also removes excessive calls to getenv() for every rendering
operation.

6e91ee071c Reimplementation of large parts of the WaveView class
The drawing itself should be unchanged but much of the rest of the
implementation has changed. The WaveViewThreads and WaveViewDrawingThread
classes were added and allow multiple drawing threads.

The Item::prepare_for_render interface is implemented by WaveView to enable
queuing draw requests for the drawing threads to process as soon as the state
change occurs during Editor::visual_changer, which often means the images will
be finished by the time they are needed in WaveView::render. This can
significantly reduce total render time and also flickering caused by images not
being ready for display.

If the drawing thread/s cannot finish the request by the time it is required in
WaveView::render then cancel it and draw the WaveViewImage in the GUI thread if
it is likely it can be completed in the current render pass/frame.  This change
also helps reduce the flickering caused by images not being ready with threaded
rendering, but with several drawing threads, drawing in the GUI thread may not
often occur (unless explicitly requested).

Allow unfinished images to be returned from the cache in
WaveView::prepare_for_render so that new draw requests aren't queued for
duplicate images. This reduces the amount of drawing for instance in
compositions where there are many instances of the same sample/waveform
displayed on the canvas as only a single image should be drawn.

Use a random width within a certain range for
WaveView::optimal_image_width_samples so that image drawing is less likely to
occur at the same time (which will cause a spike in render/draw time and
increase the chance of flickering waveforms).

Move implementations of the private WaveView classes into wave_view_private.h
and wave_view_private.cc source files.

Incorporate a fix for limiting the waveview image size to the cairo image size
limit.

mapping). This affects eg. Mixbus Strips
