James Jackson-South	4b07920c7c	Fix alpha association and SIMD rounding parity Refactors `Color` to track both exposed and stored alpha representations, adds `ToScaledVector4(PixelAlphaRepresentation)`, and adjusts pixel conversion paths so associated formats preserve canonical values without unnecessary unpremultiply/reassociate loss. This also updates equality/hash behavior to compare canonical scaled values. SIMD helpers are split into `MultiplyAddEstimate` vs `FusedMultiplyAdd`, with byte-to-float normalization updated to match scalar rounding exactly across vector widths. JPEG converters, resize kernels, and Porter-Duff/associated-alpha blending paths were updated to use the appropriate helper for either fast estimate or strict fused rounding semantics. Tests were expanded substantially (including exhaustive component/alpha cases and fused-order checks), incidental test cleanup was applied, benchmark comment snapshots were refreshed, and one black/white reference output image was updated.	4 days ago

LuisAlfredo92	6245666d61	Fixing most of things of review Also I fixed a little bug with PreviouslySeenPixels array It's weird, but I don't see any problems with encoding and the tests are ok, I wrote the memory stream to files and they look the same, but the hashes and bytes aren't the same This is very weird	3 years ago

LuisAlfredo92	07e65973a3	Finishing qoi encoder -Also adding Decode method without TPixel value -Adding stream end check to decoder (we must discuss if it's necesarry or not) -formating general code	3 years ago
LuisAlfredo92	bca998d91d	Implementing qoi decoder I need to check https://github.com/phoboslab/qoi/issues/258 because there's a bug with the decoder	3 years ago
LuisAlfredo92	a1342bf30a	Fixing Qoi detector -I had several errors about header size comparison and comparing byte arrays, but I've fixed them and tested the Identify function and it works perfect!	3 years ago
