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.
Updates #1210
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.
Updates #1212
This CL fixes the race condtion on delayedCommands, which can be
accessed and set to nil at the same time.
This CL separates some operations for delayedCommands into slow-
paths and fast-paths, and use mutex only at slow-paths for
performance. The implementation is based on sync.Once.
Fixes#1195
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.
Updates #929Fixes#1171
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.
Updates #669
Updates #759
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.
Fixes#1194
Updates #1171
This change creates a new buffered.Image even for a sub-image. This
can increase a memory usage a little, but decrease the GPU memory
usage since only the necessary pixels are allocated on a texture
atlas.
Fixes#896
Updates #1194
This change also enables to remove the optimization at
(*buffered.Image).ReplacePixels.
