/**
 * Samples the texture data at the given uv coordinate using bilinear interpolation.
 * Note this will not match GPU sampling behavior exactly.
 * Currently assumes clamping behavior.
 * @param u - The u coordinate to sample.
 * @param v - The v coordinate to sample.
 * @param widthPx - The width of the texture in texels.
 * @param heightPx - The height of the texture in texels.
 * @param data - The texture data to sample.
 * @param result - The color to store the sample.
 * @param normalizeFunc - The function to normalize the texel values. Default is to divide by 255. Pass null for no normalization.
 * @returns The result color.
