14 On some platforms, notably Windows Direct3D and Android, textures may
15 be lost at any time for events such as display resize or switching out
16 of the app. On those platforms, bitmaps created without the ALLE‐
17 GRO_NO_PRESERVE_TEXTURE flag automatically get backed up to system mem‐
18 ory every time al_flip_display is called.
19
20 This function gives you more control over when your bitmaps get backed
21 up. By calling this function after modifying a bitmap, you can make
22 sure the bitmap is backed up right away instead of during the next
23 flip.
