ebiten: Add CompositeModeMultiply (#1251) 
This change adds a new composite mode called `CompositeModeMultiply`,
which multiplies the source color with the destination color.

This is tested on Linux and Windows only.

20b5be0886 graphicsdriver: Bug fix: Tie-breaking when picking a texel 
When a texel is picked on texel-borders of a texture, the behavior
(tie-breaking) depends on GPU and unexpected. This change fixes this
issue by shifting 1/512 [texel] when picking a texel up.

1785b6a670 examples/moire: Add a smaller scale, and remove AdjustTexel function from shaders 
This can reproduce the bug reported at #669.

Apparently, the fix (8827520d4a) is
no longer required after 3550abef7a.
That's pretty odd, but examples/moire proves this fact.

2bdef2e8c4 restorable: Add an explicit way to detect context-lost 
isTexture was used to detect context-lost and called every frame.
This was not good for performance.

This change adds a way to notify context-lost from the WebGL
handlers directly, and the package restorable uses it instead of
calling (*Image).isInvalaidated.

59431e1cad graphicsdriver/opengl: Leave comments why we don't use PBO on Android 
Unfotunately, PBO might slow Android applications expecially when
coming back from context lost. Ebiten sends a lot of draw calls to
replace pixels in such case.

Until we find a good solution, let's not use PBO on Android.

52f6be2639 graphicsdriver/opengl: Fix suspicious GL function calls 
Before this change, the pixel object buffer is unbound just after
getting a pointer by glMapBuffer. This seemed suspicious.

This change fixes to do all pixel manipulations once between
glMapBuffer and glUnmapBuffer without changing a bound buffer.

This might fix a wrong rendering on some machines, but I am not
sure.
