small vulkan perf tweak. fix capturedemo over vid reloads. fix playfilm letterboxing issue. con_printf will now create consoles as needed. fix .skin compose line. fix a couple of q3bsp issues core gl contexts will no longer be given pre-core glsl shaders, is the theory. qcc now warns about unused fields. use the __used keyword to mark those fields as actually needed. use __unused to allow the qcc to potentially silently strip them. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5166 fc73d0e0-1445-4013-8a0c-d673dee63da5 2017-11-14 14:37:04 +00:00			`!!ver 100-450`
changed to not load gamecode from quake paths, to avoid issues with buggy quakeworld clients that will freely download stuff from anywhere (not sure what to do about ktx, but it can be reenabled with a cvar). image_width is now only set by a single function. tweaked scancode inputs slightly. added support for printscreen binds. changed the way gamma works. glsl gamma now used when running windows, or hardware gamma is not available. removed gl_contrast+gl_brightness. q2 gamecode support no longer has a system componant. this means that ports only need the generic stuff. misc tweaks to the d3d11 renderer. added brief descriptions to many builtins. need to add comments to constants, globals, and fields too, somehow. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4355 fc73d0e0-1445-4013-8a0c-d673dee63da5 2013-05-11 14:02:55 +00:00			`//this shader is applies gamma/contrast/brightness to the source image, and dumps it out.`
