88544fbe63 remove Sk prefix from CommandLineFlags
The command line flag package is tool-only, not part of Skia per se,
and does not need an Sk prefix to avoid naming conflicts.

And git clang-format.

9882dae24d Reduce usage of SkCanvas::flush
SkCanvas::flush is problematic and we wish to deprecate it. As a first step, this CL begins to remove Skia's internal usage of it.

Ideally clients would use SkSurface::flush and/or GrContext::flush.

82ebe04caf Reland "Add SkColorSpace factory from 3x3 row-major gamut and transfer function"
Moved named common transfer functions and gamuts to constexpr values in
SkColorSpace.h, in SkNamedTransferFn and SkNamedGamut namespaces.

Converted nearly all SkColorSpace::MakeRGB calls within Skia to use the
new factory with the named values. Multiple clients want a way to
extract named transfer function and gamut - this still doesn't provide
that, but this may be a better path forward for honestly advertising how
SkColorSpace works internally.

Originally landed as:
https://skia.googlesource.com/skia/+/a9549ab31630fc244094e6f1692371cbaf87f666

Re-landing with a new serialization format, but maintaining ability to
load old serialized color spaces, for SKP compatibility.

03115dc284 Remove xform canvas mode from Viewer, simplify color management
There are now three modes: Legacy, and Color Managed 8888 or F16. Rules
about transfer functions are gone, so allow changing gamma in either
color managed mode.

To keep things much simpler, we always construct the window surface in
legacy mode, and draw offscreen whenever we're doing any color
management. This lets us avoid re-creating the window surface when
cycling modes, and avoid making re-tagged copies when pushing color
managed images to the window surface.

b2c4ea6219 Move Views into Sample and Viewer.
What is left of the SkView system is used only by samples or viewer.
As a result, move it out of the Skia source tree and re-organize so it
is a bit easier to understand and use more shared code.

Move samplecode/ClockFaceView.cpp to samplecode/SampleTextEffects.cpp,
sice that's what's actually in it.

Move SkAnimTimer.h to tools/timer, since it's actually shared between gm
and samples.

b53f48cfec Touch input support for Windows
Had to add some logic to avoid touch and mouse cross-talk, because
(at least on my laptop), the touch screen generates both kinds of
events.

This seems really useful [1] for the many [2] Skia developers with
touch-enabled Windows devices.

----------
1: No, not really.
2: N = 1?

42bb6acf56 Simplify some Viewer code, and fix a few bugs
The content rect was always identical to the window rect,
so most of the related code did nothing. The translation
limit code is always useful (to avoid dragging the slide
way off-screen with the mouse), so always include it.
The auto-scaling to fit the screen is also still useful,
but just base it on the window rect.

The zoom code has four state variables, only used two of
them, and one was a trivially derived computation. Fold
most of that work into computeMatrix. (The translation
was always zero -- we never changed the zoom center.)

Include fDefaultMatrix in the matrix from computeMatrix,
rather than needing to apply it specially to the canvas.

Don't apply the inverse default matrix to touch or mouse
points. The absolute positions of those touch points is
not important, but because that matrix includes scale
(and sometimes very large or very small scale), it just
had the effect of greatly amplifying or damping the drag
speed. Without it, the slide always pans at the speed of
the touch/mouse drag -- which seems more desirable.

The use of the inverse default matrix was a clever trick,
but it caused the translation (applied to the global mtx)
to be scaled, so the slide was always pinned incorrectly.
Instead, supply the unmodified window rect and the default
matrix, so the trans limit code can do the obvious correct
thing: xform the slide bounds completely, then limit the
translation that will be applied after that. Slides are
now correctly pinned to screen edge regardless of how
much zoom is present in the default matrix.

Note: There are still several bugs related to all of this
code, but given the web of xform state, it's hard to
unravel. The touch gesture still doesn't know about
viewer's zoom, so that's ignored when doing the pinning.
Beyond that, it doesn't even know about window resize -
it only configures the translation limit when setting up
a slide. I had a fix for all of this (doing the
translation limiting in computeMatrix), but then the touch
gesture doesn't know about it, and can accumulate drag
motion that needs to be un-dragged to get back on-screen,
even though the slide is never really translated that far.

SkTouchGesture is in include. No one uses it except viewer:

fd8f4d502d Fix some viewer crashes when switching color mode
The whole idea of immediate mode GUIs is to put your GUI code and the
resulting action close together. Unfortunately, for actions that tear
down the backend (possibly freeing the surfaces we're drawing to), we
can't do that. So defer that action until the next frame (really, the
next idle). Only required when an action might call setDisplayParams.
