Fix: Take into account FFXI's UI Scale option when positioning the bars/text.

[joshuateveryday]

Made a quick edit to ui.lua. Basically you just need to account for UI Scale when positioning the hotbar. Sorry for the quick and dirty copy/paste, didn't have my git pipeline set up on the PC I'm making edits on.

I play FFXI in 5K so I have to scale my main fullscreen window up to 2.0 on the UI Scale.

Then when I launch mules, my hot bars are positioned wrong because the have the incorrect OffsetX/OffsetY used by the 5k resolution window. (Mules use 2K resolution with a 1.0 UI scale)

-- setup positions and dimensions for ui
function ui:setup_metrics(theme_options)
    self.hotbar_width = (400 + theme_options.slot_spacing * 9)

    local settings = windower.get_windower_settings()
    -- Calculate UI Scale
    -- Need to take into account users who are using UI Scales > 1.0 in windower.
    local ui_scalar = ((settings.ui_x_res * 1.0) / (settings.x_res * 1.0))
    self.pos_x = ((settings.x_res * ui_scalar) / 2) - (self.hotbar_width / 2) + theme_options.offset_x
    self.pos_y = ((settings.y_res * ui_scalar) - 120) + theme_options.offset_y

    self.slot_spacing = theme_options.slot_spacing

    if theme_options.hide_action_names == true then
        theme_options.hotbar_spacing = theme_options.hotbar_spacing - 10
        self.pos_y = self.pos_y + 10
    end

    self.hotbar_spacing = theme_options.hotbar_spacing
end
