library_webgl.js attempts to use a pool of temp float or int buffers for uniform uploads up to 288 elements, however it would only allocate 288 temp buffers, so 0 through 287 would be fine but 288 would crash (miniTempWebGLFloatBuffers[288] would be undefined).
Confirmed manually that any one of the six "Just at the optimization limit" calls would crash before, and with the fix does not.
