Font render: LOVE's anti-alias pixels look somewhat nicer (although it seems to have a sizing bug)

[morew4rd]

• Red boxes are 64x64 pixels and 64 pixels apart
• Font is loaded with 64 pix height

lyte2d code:

local font = lyte.load_font("assets/DroidSansMono.ttf", 64)

lyte.set_font(font)

function lyte.tick()
    lyte.cls(0, 0, 0, 0)

    lyte.set_color(1,0,0,1)
    lyte.draw_rect(10, 10, 64, 64)
    lyte.draw_rect(10, 10+128, 64, 64)

    lyte.set_color(1,1,1,1)
    lyte.draw_text("Hello, wow 1", 10, 10)
end

love2d core:

local font = love.graphics.newFont("assets/DroidSansMono.ttf", 64)

love.graphics.setFont(font)

function love.draw()
    love.graphics.setColor(1,0, 0, 1)
    love.graphics.rectangle("fill", 10, 10, 64, 64)
    love.graphics.rectangle("fill", 10, 10+128, 64, 64)

    love.graphics.setColor(1,1,1,1)
    love.graphics.print("Hello, wow " .. love.graphics.getDPIScale( ), 10, 10)

end

Needs investigation for the differences in size.

Also, LOVE2D's anti-alias pixels look somewhat nicer. Why?

With a potential fix/improvement:

Top is LOVE (not sure why it's big, but on Linux it seems properly sized)
Middle is current Lyte2D
Bottom is "improved" Lyte2D

May have found why LOVE renders things large on my Windows machine: https://love2d.org/forums/viewtopic.php?t=81236

(I have a high res monitor so I have to make my display %125 for readability.)

With that workaround, LOVE now renders boxes with the right size, and the window size is also correct, however, LOVE font rendering seems wrong to me. It's too big, and incorrectly positioned:

Another note: LOVE has a PR for using FreeType's SDF rendering (not accepted, still open: love2d/love#1966)

Let's take a look at this as well.

OK closing this. In the future, we can take a look at SDF.
