[PATCH 0/1] MR7703: d2d1: Add [loop] attribute in sample_gradient() shader function.
Skips loop unrolling when compiling the shader, which lowers compilation time from ~80ms to ~40ms on my machine, which might preempt stutters for applications that call d2d_device_context_init() many times. This can help [CW bug 25000](https://www.codeweavers.com/support/bugs/browse/?cmd=bug_edit;bug_id=25000). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7703

Either that, or we could compile this once. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7703#note_99430
I would recommend doing both things. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7703#note_99910
