-- shapes.lua - Minimap shape masks for SexyMap OctoWoW Edition
-- Provides CApplyShape() which clips the minimap to a given shape
--
-- Uses Minimap:SetMaskTexture() to clip the minimap to a given shape.
-- The "Square" shape uses the WoW built-in WHITE8X8 texture which removes
-- the circular mask entirely, showing a true square minimap.
-- For other shapes, addon-local BLP mask textures are used.

local _G = getfenv(0)

-- Shape texture paths
-- For addon-local BLP files, do NOT include .blp extension - WoW's SetMaskTexture
-- auto-appends it (same as SetTexture). For built-in WoW textures, use full paths.
