Blend modes available for TextmodeLayer compositing in 2D mode.

• 'normal': Standard alpha compositing. Opaque layer pixels fully replace the base; translucent pixels fade in.
• 'additive': Layer color is added on top of the base. Great for glow/energy effects but will clip as values approach white.
• 'multiply': result = layer * base. Darkens wherever both layers have color; any channel multiplied by 0 becomes 0.
• 'screen': Inverse of multiply. result = 1 - (1 - layer) * (1 - base). Preserves highlights while lightening midtones.
• 'subtract': result = base - layer. Useful for cutting out or darkening effects.
• 'darken': Takes the minimum of layer and base per channel. Only darkens; never lightens.
• 'lighten': Takes the maximum of layer and base per channel. Only lightens; never darkens.
• 'overlay': Combines multiply and screen. Darkens darks and lightens lights, increasing contrast.
• 'softLight': Softer version of overlay. Subtle contrast enhancement.
• 'hardLight': Like overlay but more intense. Uses blend color to determine multiply/screen.
• 'colorDodge': Brightens the base by the blend color. Creates intense highlights.
• 'colorBurn': Darkens the base by the blend color. Creates deep shadows.
• 'difference': result = |base - blend|. Creates inverted/solarized effects.
• 'exclusion': Softer version of difference. result = base + blend - 2 * base * blend.
