609a3c4e22 ebiten: Bug fix: Fix the texel calculation 
In shaders, texCoord is always in texture0's texels. Convert them
at imageNTextureAt functions correctly.

Fixes #1290

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.

8fd377f1e3 driver: Add ImageID and use this 
This is a preparation to introduce shaders. Shader programs
require images as uniform variables, but the current way would make
API complex unnecessarily.
