This pr allows for configuring the framerate target and adds support for two other framerate targets, a "fastforward" and "slowmo" target which can be enabled via either a toggle or holding a button.
this allows for supporting a more accurate framerate target and allows for users to slow down the speed of gameplay if they so desire
* maintain precision until all lights are calculated
fixes lugia on the soul silver title screen
* small optimization
* small note
* small cleanup/notes
shouldn't need to check that every time, since the variable shouldn't be able to overflow
* hw doesn't cap difflevel at 255
Should it cap at all?
Can vtx colors overflow...?
* diffuse level appears to be shifted right by 9
fixes some minor inaccuracies
* improve specular lighting a little
* small improvement to diffuse lighting
fixes a few off by ones
- finding by azusa
* small tweaks
* handle overflows of diffuse lighting properly
-credits to azusa once more
* attempt at improving specular lighting calcs
still far from correct, but its a start.
fixes: https://github.com/melonDS-emu/melonDS/issues/1545
* meh
* improve specular lighting further
* add notes
* theory: add half vec instead of subt 1
* implement azusa's specular lighting algorithm
* fix minor edge case with spec lighting
* give proper credit in comments
* fix some bugs/misc tweaks
* more quirky overflow/underflow handling
* fix a spec lighting edgecase
remove some redundant parentheses
* fix an edge case with light vector calcs
* spec recip uses a different calc for light dir?
also remove a check that shouldn't be mathematically possible to trigger
* nvm that thing i thought couldn't trigger was required
also move reciprocal calc into the light vector calc function since i might as well now ig
* replace a bunch of stuff with much *much* simpler algorithms
* misc cleanup
PARENTHESES WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
* leave a note abt shininess table's default value being incorrect
* Resolve symlinks to avoid including the same thing twice (like
version-numered dylib symlinks)
* Look in all Qt prefix paths for plugins - the package may not
necessarily have the same path
* reduce install_name_tool invocations to make it a bit faster
* change dylib IDs to remove original source path
