The Map, Track Design List, Track Design Placement, Install Track, and Park Preview windows all shared a single SPR_TEMP sprite ID for rendering dynamic preview images. In OpenGL mode, this caused them to overwrite each other's textures when multiple windows were open simultaneously. To fix it I added separate temp sprite IDs for each window that needs one, with an array of G1Elements to store each separetely
