abdcc5f5b4 Add text rendering related overrides to Viewer.
This combines the AAA and DAA settings into one Antialias setting which
also exposes alias and normal settings. It also fixes restoring the AAA
and DAA global state when not overriding.

This adds hinting, subpixel positioning, and subpixel rendering
tri-state toggles as well.

d67e518980 Move ImGui support code to ImGuiLayer
Viewer still has plenty of code that uses ImGui to create application
specific UI, but the structural code that forwards input to ImGui, and
converts per-frame ImGui rendering data to Skia draw commands is now in
a single component that can be reused in any sk_app-based application.

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.

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.

79086b94ed Integrate the ImGui library with viewer
Code and docs are at: https://github.com/ocornut/imgui

ImGui is an open source immediate mode GUI library that's
lightweight and fairly simply to integrate. Widget functions
return their state, and the library emits vertex and index
data to render everything. It's got a huge set of built-in
widgets and really robust layout control.

For the initial integration, I had to fix up event handling
in the viewer's app framework (to get mouse wheel and more
keys, etc...).

The new viewer 'Debug' window is toggled with the space bar.
For this change, I've added one feature to that window: the
slide picker. It's got a list of all slides, with filtering
support, and the ability to click to switch slides.

I also included the ImGui 'Demo' window (toggled with 'g').
This is nicely laid out, and includes examples of pretty
much everything the library can do. It also serves as good
documentation - find something that looks like what you want,
and then go look at the corresponding code (all of it is in
imgui_demo.cpp).

I have other CLs with other features (like directly editing
the primaries of the working color space), but I wanted to
land this chunk first, then start adding more features.

Other than adding new debugging features, there are few
more outstanding work items:

1) Raster doesn't render the GUI correctly, due to non-
invertible pos -> UV matrices. Florin is working on that.
2) Touch inputs aren't being routed yet, so the GUI isn't
usable on Android yet. Might also be tough to work with,
given the size.
3) ImGui has clipboard integration (that's why it wants
the C, X, and V keys), but we need to wire it up to the
OS' clipboard functions.
4) Draw commands can carry a void* payload to support
drawing images (using whatever mechanism the engine has).
I'd like to set that up (probably using SkImage*), which
makes it really easy to add visualization of off-screen
images in GMs, etc...

f750fbcb69 Simplify viewer's handling of backbuffer surface and color space
WindowContext still supports color spaces, but not other color
types. Any off-screen rendering is the app's responsibility.

This change also adds (working) F16 support to viewer. Note that
the previous 10-bit and FP16 support in WindowContext was broken.
There was no code to push the off-screen canvas to the window.
If you ever made it to the unreachable off-screen code path in
createSurface, it would have simply stopped drawing.

The decision to limit the window's gamut to sRGB is mostly driven
by my desire to add real-time editing of gamut. This design lets
us do that, without tearing down and rebuilding the window for
every change. An application could still supply a different gamut
via setDisplayParams and render directly to the back buffer with
proper color correction.

622c8d5de1 Add flexible keybinding/command system to sk_app.
Viewer demonstrates use: Just create an instance of CommandSet,
register with the window, and add commands. Hopefully, we can keep
all commands in one place, and get some nice side-benefits. With
this framework, if you want to add a new command, you are only
required to add code in ONE place. And you get added to the help
screen, for free.

CommandSet automatically binds 'h' to cycle through the help modes.
(Functional grouping is most useful for general use, but the other
mode is nice to know what a key does, or to find an unused key for
a new feature).

05de216ffb Add sRGB mode toggle to Viewer.
Unlike SampleApp, this just switches out the format of the window
surface (and then adjusts the gamma-correct flag on the SkSurfaces).
