a4e669cc39 ebiten: Avoid using SubImage for stretching test 2020-07-15 23:49:26 +09:00
Hajime Hoshi
2a9fd5ef13 mipmap: Avoid using the vertex backend when GopherJS is not used 
The backend logic is especially for GopherJS. As the backend logic
tends to consume a lot of memory, let's avoid this when possible.

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.

484473b6d9 graphicscommand: Span to 1/3 pixels 
The center of pixels is problematic as the behavior depends on GPU.
In order to avoid this, align the vertices with about 1/3 pixels.

d74f7d3a77 shareable: Add gaps between images 
After this change, each image on the texture atlases has a
transparent border around it.

This change removes the hack to round texels not to violate the
source regions.

1d701577d6 buffered: Use the pending pixels when possible at At 
(*Image).At can be unnecessarily slow since this tries to get
pixels from GPU. This change reduces the chance to read GPU by
using its pending pixels when possible.

aa6fc67736 Revert "graphics: Avoid all copying pixels" 
This reverts commit c60a32a479.

Reason: This breaks backward comptibility and it was not obvious how to fix examples.
