* Colors in pixi are premultiplied.
* Pixi blending modes are modified to work with premultiplied colors. We cannot create custom blending modes.
* Textures are loaded as premultiplied (see assers/atlasLoader.ts: alphaMode: `page.pma ? ALPHA_MODES.PMA : ALPHA_MODES.UNPACK`):
* - textures non premultiplied are premultiplied on GPU on upload
* - textures premultiplied are uploaded on GPU as is since they are already premultiplied
*
*
* We need to take this into consideration and calculates final colors for both light and dark color as if textures were always premultiplied.
* This implies for example that alpha for dark tint is always 1. This is way in DarkTintRenderer we have only the alpha of the light color.
* If we ever want to load texture as non premultiplied on GPU, we must add a new dark alpha parameter to the TintMaterial and set the alpha.
