4021c24534 shader: Separate uniform variables and texture variabls
Textures cannot be treated as a regular variable, then they should
be treated differently from other uniform variables.

Add a new function texture0At replacing texture2D.

2a63512c6e driver: Add AddressUnsafe
This skips the source-region check and reduces 'if' branches from
shader programs.

AddressUnsafe is internal only so far. We might expose this value
later.

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.

This is a preparation to introduce shaders. Shader programs

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.
