41f060b1d2 ebiten: Use the common vertices backend at DrawTriangles 2021-03-20 20:25:42 +09:00
Hajime Hoshi
26b9fa20c1 internal/graphics: Bug fix: Race condition at QuadVertices 
QuadVertices or verticesBackend.slice reused its backend slice.
This caused a race condition. QuadVertices can be accessed from
multiple goroutines, and resetting the head and copying the data
at internal/graphicscommand might not be synced.

This change fixes this issue by basically reverting
9cb631e30f.

Closes #1546

5a62587df5 ebiten: Bug fix: The vertex backend was not flushed when the screen is shrunk 
The last parameter of QuadVertices represents whether we can flush
the backend vertices (on Wasm). The problem was that this was
unexpectedly false even though the image is the screen, when the
screen rendering is done with FilterLinear instead of FilterScreen.

Closes #1479

c7330883ef restorable: Remove Fill and make (*ebiten.Image).Fill available for sub-images 
Now a scissor (a clipping region) can be specified, we don't have to
worry about the rendering results out of the specified region.
Replace the implmenetation of the Fill with just a DrawTriangles with
an empty white image.

As a side effect, SubImage is avilable for Fill.

0c70823f27 graphics: Delay draw commands and execute them only when needed 
This change introduces a queue for delayed graphics commands.

execute them.

This reduces the number of draw calls especially for the launching
phase.

d2312f1450 shareable: Lock before BeginFrame 
This make package shareable more consistent. The mutex is lock
after EndFrame and before BeginFrame, and the similar rule will be
applied at launching (BeginFrame unlocks the lock in any cases).

Instead, package ebiten queues image operations if BeginFrame and
doesn't create provisional non-shared images. This should improve
performance at launching since this reduces the number of draw
calls, especifally for creating new images.

3960a4bbdf restorable: Add (*Image).Fill 
This resets the infomation for restoring if possible. This makes
it more efficient to use offscreens.

b8eeded538 graphics: Remove 'resetRestoringState' 
This is basically a revert of 2d079b123f

As filling can happen on a part of a shared image, resetting the
restoring state was wrong.

b210339786 graphics: Use 'negative' mipmap when enlarging a too small image 
This is a hack to render edges correctly.

This works only when the filter is nearest.

2d079b123f restorable: Add ResetRestoringState to reset the state 
After Fill command, the image doesn't have to keep the restoring
information. Now Fill command is as same as DrawTriangles, there
is no way for restorable.Image to know whether it can reset the
state or not. ResetRestoringState clears the state explicitly.

Package shareable should take care of this.

Finalizers are called at arbitrary timing in a different goroutine
and might cause tough problems. This might be related to #821.
