In `internal/uidriver/glfw/run_notsinglethread.go`, if the `UserInterface.init()` function returns an error, the `loop` is
executed regardless and the error is discarded. This behavior will hide the error returned by `init()` and might trigger
some crashes (see #1688).
A partial fix was implemented in 6c4edf8 , however that commit alone is not enough: the code now is correctly returning
the error via the `ch` channel, but it still executes the `loop()` function. This merge request skips `loop()` call if `init()`
had an error.
Updates #1688
This is basically a reland of 9cb631e30f.
This change locks the vertices backend at the end-frame phase to
protect from vertices usages by other goroutines.

Using restorable images is expensive as this sometimes requires to
load pixels from GPU. On browsers, just reloading the application
should be fine when the context lost happens.
Closes#1603
PBO was introduced to improve the performance at ReplacePixels,
but we found that PBO can degrades the performance. Also, now
multiple glTexImage2Ds are called successively like a batch, so
the situation is now different from that time when PBO was
introduced.
Let's remove PBO usages and wait and see.
Closes#1678
IsWindowBeingClosed reports whether the window is being closed by
the user.
SetWindowClosingHandled sets whether the window closing is handled
or not. If the state is true, the window is not closed immediately
by the user and the game can handle the closing state. In this case,
the Update function should return an error in order to end the game.
This change also adds examples/windowclosing.
Closes#1574
Callbacks created by NewCallbackCDecl were never released and then
they are leaked, especially when the window size was changed by
SetWindowSize on Windows.
This change defines new callback ID types with uintptr, and reuse
the callbacks.
Closes#1672
This reverts commit ecc8514d4b.
Reason: This doesn't fix the issue. gomobile assumes the existence of $GOPATH/pkg/gomobile, so leave it as it is.
