610ebbbab5 ebiten: Bug fix: zeroUniformValue panicked with vec2 or other vector/matrix types 2021-10-30 04:30:29 +09:00

06f4142ca0 internal/driver: Optimization: Replace interface{} with driver.Uniform 
Converting a value from/to interface{} can create a value in heap
and this is not efficient.

abbb929148 ebiten: Bug fix: Wrong uniform type was used 
This change also includes PanicOnErrorAtImageAt, which panics when
an error is detected at (*Image).At. This function is only for testing.

70acb9c1f6 shader: Rename shader bultin functions 
Renamed image0TextureSize to imageSrcTextureSize, and removed the
other texture-size functions.

As texture-coordinates are always in image0's texture texels,
calculations with texels are always done with image0's texture texels.
Then, other texture-size functions are useless. To avoid confusion,
let's remove the functions and leave the necessary funciton.

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