[PATCH 0/1] MR7703: d2d1: Add [loop] attribute in sample_gradient() shader function.

[Francisco Casas (＠fcasas)]

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).

Either that, or we could compile this once.

[Elizabeth Figura (＠zfigura)]

I would recommend doing both things.
