151dfffad6 internal/restorable: simplify canDetectContextLostExplicitly 
This constant was set with some wrong assumptions:

 1. On Android, recovering was needed.
 2. On iOS, OpenGL ES was used when
    a. The architecture was 386 or amd64 == an emulator is used
    b. The build tag ebitengl was not specified
    c. gomobile-build was used
 3. On browsers, recovering was needed.

1., 2b, and 2c are correct.

2a. is not correct: Now emulators are available on all the
architectures with both Metal and OpenGL.

3. is not correct: Ebiten no longer recovers the contest lost.

Now, Ebiten can detect a context lost explicitly when

 1. On Android
 2. On iOS and on gomobile-build
    (When gomobile-build is used, OpenGL should always be used)

Based on this fact, this change changes the constant to a variable,
and fixes the logic to set the variable.

81b9f91f86 internal/graphicscommand: compile shaders lazily 
With DirectX, the graphics driver cannot be determined until the
main loop starts, as a transparent window cannot be treated with
DirectX so far. On the other hand, compiling shaders requires a
graphics driver as it requires information about Y directions of
NDCs and framebuffers.

This change delays compiling shaders until the graphics commands
are actually executed in the main loop.

c1a0d83f8d internal/restorable: simplify the implementation of rect 
Allow overlapped regions at pixelsRecords.

This removes the members `last*` for caching. These were introduced

are no longer needed.

54b4e87506 internal/restorable: bug fix: ReplacePixels on a sub-image might panic on Android 
If regions by ReplacePixel are overlapped, this can panics. This can
happen only on Android, where a context lost can happen.

Thus, a sub-image cannot call a direct ReplacePixels. internal/buffer
has to care this.

6ba6cdc721 restorable: Bug fix: Dispose all the image before start restoring 
A current texture ID and a new texture ID can be duplicated.
Disposing part of textures and creating textures at the same time
can make contradicted situation.

Only finalizers are problematic since they can stop everything,
but other things are not. Let's care finalizers and just use
regular locks.

Fixed a bug that an image passed to Apply might not be initialized,
and there was no correct way to treat such an image. Now Apply
accepts only an initialized image.

2d079b123f restorable: Add ResetRestoringState to reset the state 
After Fill command, the image doesn't have to keep the restoring
information. Now Fill command is as same as DrawTriangles, there
is no way for restorable.Image to know whether it can reset the
state or not. ResetRestoringState clears the state explicitly.

this shortcut was originally useless.
