The idea is that the gradient cache tries to only keep a certain amount
of texture memory cached. It sounds like that limit is too low --
indeed, it is set at 4096 which is only 16k, or roughly 4 gradients.
That would be better with

#define CAIRO_GL_GRADIENT_CACHE_SIZE 16384

judging by desktop usage, and you probably have a better idea for your
use cases.
