There are two new encodings, direct and indirect.
The indirect encoding, or at least some way to water down a custom palette
color, is necessary for icons like
https://raw.githubusercontent.com/google/material-design-icons/master/device/svg/production/ic_signal_wifi_2_bar_48px.svg
which say `<path fill-opacity=".3" d="etc">`. Rendering such icons need a
partially transparent version of a custom palette color, e.g. the theme
foreground color, which could be black for a traditional theme or white for a
dark theme.
The direct encoding doesn't offer anything beyond the existing 4 byte encoding,
other than being a shorter encoding. It could come up relatively often, though,
if e.g. the suggested palette's elements are all fully opaque. Reserved styling
opcodes aren't particularly scarce, so I think it's a win overall. I think we
might as well add it now, if we're adding the 3 byte indirect encoding, and
avoid re-basing the other opcodes again if we added it separately.
Also fix some opcode typos in encode.go, with TODOs for more tests.

"man shmget" suggests that the IPC_CREAT flag isn't necessary if the key

The best fix, for the Go code, is to delete all mentions of ipcCreat.

A *glwidget.GL renders OpenGL calls into a shiny widget.
It is analogous to NSOpenGLView or GLSurfaceView.
This first version is extremely inefficient, it copies the pixels back
from the GL view to main memory, and then lets the gldriver copy it
again to a texture. But it gets the separate context concept clear,
and efficient rendering can be done in a later CL when the Paint method
has some reasonable way of accessing a Window's underlying GL texture.
It is in its own package to avoid adding a gldriver and cgo dependency
to the widget package.
This CL only contains X11 support, OS X will follow later.

This means that out-of-bound texture reads return the in-bound edge
values instead of returning zero. Since the picture filter is
"bilinear", this is noticeable when scaling the entirety of the texture
(when srcRect = tex.Bounds()), such as in the example/fluid program.
Before this commit, the edges in the destination window were feathered.
After this commit, they are crisp, the same as the gldriver.
