There is no way to distinguish an unknown format from
Mono8 because Mono8 is zero. The current CL fixes this
issue by starting the format constants from iota + 1.

Embedding is more trouble than it's worth. For example, the image/draw
package will pick the slow code paths for an embedded *image.RGBA.

This is done by moving app.Context to internal/mobileinit,
introducing mobileinit.SetCurrentContext and,
making bind/java depend on it.

There is currently one usage of "an" prior to "PCM". The indefinite
article usage prior to an acronym is determined by the
pronunciation of that acronym's first letter. If the pronunciation
starts with a consonant, "a" is used. If the pronunciation starts
with a vowel, "an" is used.
Usage

Note that there is currently a correct usage in the same file on a
different line: "a PCM header"

This CL reverts the changes made in golang/go#11299.
Allowing creation of multiple contexts break the case of multiple
third party packages depending on the al bindings. These packages
need to make sure that there is a valid current context or initiate
and make a context current. Packages racing to create and make a
context current is what we would like to avoid.
Therefore, al bindings will support only a single context that is
initiated during OpenDevice.
Fixesgolang/go#11385.

Ever since we moved to a bitmap font instead of using freetype, the backing
image's dimensions are 43x9, not 50x12, and we might as well match. For
example, the output will be exactly 43x9 pixels at 72DPI, or 86x18 pixels at
144DPI, etc.

In the long term, a lot of this package should be removed in favor of the
golang.org/x/image/math/f32 package. The latter is the common location for
matrix types shared across graphics libraries. For example, the
golang.org/x/image/draw package refers to golang.org/x/image/math/f64.

This change will break Darwin. I have only built and tested this on
desktop linux and Android linux. A follow-up CL will fix Darwin.
Currently, OpenGL gets its own thread, and UI C code (e.g. the Android
event loop, or the X11 event loop) gets its own thread. This relies on
multiple system-provided UI-related C libraries working nicely together,
even when running on different threads. Keeping all the C code on the
one thread seems more sound.
As side-effects:
- In package app/debug, DrawFPS now takes an explicit Config.
- In package app, some callbacks now take an explicit Config.
- In package exp/sprite, Render now takes an explicit Config.
- In package event, there are new events (Config, Draw, Lifecycle),
and an event filter mechanism to replace multiple app Callbacks.
- In package geom, the deprecated Width, Height and PixelsPerPt global
variables were removed in favor of an event.Config that is
explicitly passed around (and does not require mutex-locking).
Converting a geom.Pt to pixels now requires passing a pixelsPerPt.
- In package gl, the Do, Start and Stop functions are removed, as well
as the need to call Start in its own goroutine. There is no longer a
separate GL thread. Instead, package app explicitly performs any GL
work (gl.DoWork) when some is available (gl.WorkAvailable).
- In package gl/glutil, Image.Draw now takes an explicit Config.
Callbacks are no longer executed on 'the UI thread'.
Changing the app programming model from callbacks to events (since a
channel of events works with select) will be a follow-up change.
