1fe2f47701 graphicscommand: Remove the source-region parts from the uniform variables 2020-06-30 00:44:05 +09:00
Hajime Hoshi
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.

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.

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.

graphicscommand: Return the error immediately (#1060) 
Now grpahicscommand saves the error and shows the error after a
while. This was good to simplify the API but was the cause to hide
some issues.

This change fixes all the errors to be returned immediately, and
buffer this in the ebiten package instead.

0c70823f27 graphics: Delay draw commands and execute them only when needed 
This change introduces a queue for delayed graphics commands.
When an image's pixels are retrieved or the screen is rendered,
Ebiten calculates the set of the necessary draw commands and
execute them.

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

cddb93b9f6 graphicscommand: Move the texel adjustment logic to graphicscommand package 
This is a preparation for #879. The value of the texel adjustment
depends on the graphics driver (GLSL float precisions), and this
can be accessed only after the run loop runs. The place where
graphics commands are executed seems an appropriate place.
