  "message": "Performance improvements for gradients (#1098)\n\nThis PR contains a number of changes to improve the performance of\ncomplex paints:\n- Instead of wrapping each painter in a `Box`, we use generics. I\nchecked the changes in my C wrapper library and it didn\u0027t have any\nnoticeable impact on binary size, which makes sense because the\n`paint_u8` and `paint_f32` methods are probably never inlined. However,\nit does feel like it might have impacted compilation time a bit, but I\nhaven\u0027t measured it. But this is definitely a necessary change, as the\n`Box` allocations really showed up in the profiles (~20%).\n- I implemented an optimization for SRGB gradients so we don\u0027t create\nadditional stops which are unnecessary.\n- I slightly reduced the size of the LUT table for certain number of\nstops, but this should still be more than sufficient (and also matches\nBlend2D).\n- I SIMDified and optimized the actual LUT computation.\n\nHere is a comparison of rendering times for linear gradients, the gains\nare especially noticeable for smaller sizes, but also the biggest one\nhas gotten quite a bit faster thanks to the removal of `Box`.:\n\nBefore:\n\u003cimg width\u003d\"1349\" height\u003d\"723\" alt\u003d\"image\"\nsrc\u003d\"https://github.com/user-attachments/assets/5b162d17-134f-44c6-b478-d85598c1de2f\"\n/\u003e\n\n\nAfter:\n\u003cimg width\u003d\"1348\" height\u003d\"727\" alt\u003d\"image\"\nsrc\u003d\"https://github.com/user-attachments/assets/0d61c65f-91cb-4c5d-b895-52e921478c1c\"\n/\u003e",
