Use SDL_GameController instead of SDL_Joystick where possible
SDL_GameController provides mappings between axis and button indices and a
general layout that is similar to a XBox 360 controller. Since this layout is
common, these changes allow creating proper controller mappings for a large
variety of gamepad/OS combinations out of the box.
Change initially provided by EACFreddy. Fixed multiple crashes due to a stale

master doesn't support SDL1 anymore.
There's a strange stick drift problem. It might be my controller but
it'll have to be investigated further.

Another flag bites the dust. This time: -ffinite-math-only.
Since GCC 5, with this flag set, NaN compares equal to zero in some cases but
not others. Causes e.g. "attempted division by zero" error spam from this QC

float x = nan("");

Redesigned TaskQueue to have a queue and distributor model so that threads can keep their own queues of work to do without locking to check for more work. Tasks are not executed until TaskQueue_WaitForTaskDone calls TaskQueue_DistributeTasks.
Added a fast path to TaskQueue_DistributeTasks for tasks that are waiting on other tasks to finish first, they are simply dequeued and re-enqueued immediately, and tend to just live on the distributor queue.
TaskQueue thread count is now dynamically adjusted based on tasks being queued per frame, and has a minimum and maximum thread count.
TaskQueue threads now sleep when idle, this may not be ideal, but did substantially lower the cpu usage so that it doesn't make other applications relatively unresponsive like it did before.

Overhauled bouncegrid light splatting for performance reasons - instead of a series of radial dots being accumulated in the texture, it is spherical distance from line segment calculations performed at each pixel, optimized to process pixels in order (filtering down the list of splat paths in each loop). This is a big framerate increase (as raytracing was not the bottleneck at all), and could be threaded in theory.
This required rebalancing the way that spacing interacts with quality, and the conespread parameter has been eliminated (as measuring distance to a non-uniform capsule seems especially challenging, but maybe that could be added back someday), so all parameters have changed a bit.
