            Enable support for FreeType fonts (TTF/OTF).
            This requires the FreeType library to be enabled.

            When enabled, you can use TrueType and OpenType fonts.

            Enable support for JPEG decoding in EAF (Emote Animation Format).
            This requires the ESP JPEG decoder component to be enabled.

            When enabled, EAF files can use JPEG encoding for image blocks.
            When disabled, JPEG encoding will not be available, reducing code size.

                Do not blend partially covered pixels whose centre is outside

                For opacity=255 polygon fills, write the fill colour directly
                for inward edge pixels instead of blending coverage with the
                destination framebuffer. This is faster and prevents colour
                contamination, but the edge is less smooth.
