// Alpha is the alpha value (0-255) to use when blending the source image with the destination image.

// If color_palette is not NULL, it is used to map the source image's 8-bit Y to an 16-bit RGB565 color.

// Valid Hint Flags:
|
|
//
|
|
// * IMAGE_HINT_BILINEAR: Use 2D bilinear interpolation when scaling the image versus nearest-neighbor.
|
|
// * IMAGE_HINT_HMIRROR: The destination image result should be horizontally mirrored from the source image.
|
|
// * IMAGE_HINT_VFLIP: The destination image result should be vertically flipped from the source image.
|
|
// * IMAGE_HINT_BLACK_BACKGROUND: The destination image should be considered to be black (0) for alpha blending.
