getSystemLimits seems to report an msaa value higher than is actually supported

[radgeRayden]

Using the following code:

local lg = love.graphics
local msaa = lg.getSystemLimits().canvasmsaa

lg.setBackgroundColor(.8, .9, 1)
lg.setNewFont(14)
love.window.setMode(240, 240, {msaa=msaa})

function love.draw()
	for i=40,200,40 do
		for j=50,170,40 do
			lg.setColor(0,0,0)
			lg.print("Generated with MSAA: "..msaa, 10, 10)
			
			lg.circle("fill", i, j, 20)
			lg.setColor(1,1,1)
			lg.circle("fill", i, j, 17.8)
			
		end
	end
end

Even though my GPU reports an MSAA value of 32, the rendering looks as if no MSAA was applied. Manually setting the value to something reasonable like 8 yields the expected result.

Renderer info:

OpenGL 3.3.0 NVIDIA 516.59 NVIDIA Corporation NVIDIA GeForce RTX 3080/PCIe/SSE2

OS is Windows 11.

In love 11, canvasmsaa is independent from the max backbuffer MSAA.
