FSO doesn't appear to use this any longer. And even when it was enabled the
requirements made it largely useless anyway. Removing to clean up cfile a
bit and so we don't have to keep maintaining it.
This adds a mechanism for running generic operations at specific points
of the frame execution. This can be used by any part of the code an not
just Lua since it simply executes std::functions. It also adds an
"execution context" concept that specifies in which situation an
operation should be executed.
This is then used by the Lua Coroutines code for resuming coroutines at
specific points instead of always when the awaited promise resolves.
This was requested by Axem for improving the usability of FSO
screenshots. This will remove the need to convert the TGA files to PNG
before uploading them to an online image hoster.
PNGs can have 16 bits per channel but we always tell libpng to reduce
that to 8 bits per channel. However, we do not tell the caller of
png_read_header that this will happen so instead of 32-bits per pixel,
we tell bmpman that the image has 64 bits per pixel which causes some
issues.
The specific issue I fixed was the system map of BtA where the jump
nodes used a 16-bit PNG which broke the alpha blending of those bitmaps
since bmpan though that the image had no alpha channel.
Main use case is headanis where only one is played at a time and
caching the frames merely increases memory use & fragmentation, leading
to malloc errors with heavy apng use
I didn't read the spec correctly; only the previous frames portion of
the output buffer is supposed to be cleared/reverted; not the entire
output buffer
Handle total_time directly requested from bm_load_animation
Make generic_anims request total_time directly
Move png-vs-apng check to apng class
Remove redundancy in apng exception messages
Update comments
i.e. apngs (pre)loaded into bmpman slots
handles apng variable frame delays
Includes new lua function (getFrames) to find the current frame for
apngs. Also uses new function to correctly display apngs for mission
loading animations, ship thrusters & engine glows.
includes:
full-colour & hud-colour headanis
cbanims & intelanims
mainhall animations (including playing in reverse)
Notably does not support ship/weapon select anims as they need
keyframes and there isn't anywhere to specify them in the apng format
libpng now at 1.5.2 (with update to pngutils)
zlib now at 1.2.5
(Files are in "LF" instead of "CRLF" this time around.)
MSVC6-2010 and XCode project updates included.
Adds PNG to Maps (should only be used for Nameplates), Interface, Effects, HUD (still needs HUD Rewrite to implement), Player/Squad Images, Multi Players, Multi Cache, CB Anims and Intel Anims.
LIBPNG: Version 1.2.42, current and highest usable version (MAX_VERSION), Linux can use any 1.2.2x-1.2.42, but should NOT use 1.4.0 under any platform for ANY reason (will require rewriting pngutils)
ZLIB: Version 1.2.3.
