c845675b9b - Fixed: When using PALVERS on the sky, it used the scaling from the true color version. (Side Note: I changed a line that scales the sky position according to the y scaling factor. This is because a 2x high resolution sky at 2048x256 wasn't positioned the same as a 1024x128 unscaled version. I moved the expression to the > 200 height path only, but I'm not sure if it's even still needed.)
- Fixed: PALVERS crashed with unknown textures since a value was never given for %s.
- Fixed: FON2 loader didn't set ActiveColors correctly.

5bfcaab25c - separation of software renderer from the rest of the code complete. All external access to the renderer is routed through the FRenderer interface class now, with two exceptions (2D texture drawing to a canvas and polymost testing code) that are handled by #defines.

17ed7aaabd - moved the code from r_data.cpp to some better fitting places and deleted this file and r_data.h because the remaining parts of it were just a random collection of unrelated functions.

6309d90be0 - moved texture counting code into FTextureManager.
- moved all code and data for Build tile management into FTextureManager.
- moved texture animation management into FTextureManager.
- changed: Animate textures only once per frame, not per view. Otherwise with animations that have sub-frame accuracy camera textures of the same area can show different animation frames if the frame changes falls between the rendering of the different views.

b57ac1aed8 - added a r_scaletallskies CVAR so that sky positioning can be checked
more easily.
- fixed: Skies with a height of exactly 200 pixels should not be stretched.

84fda053ba - More sky changes: Textures taller than 200 pixels but shorter than 241
are scaled to the height of a 200 pixel tall sky. Skies taller than 240
  use the same scale as a 240 tall sky but are shifted down to make the
  top of the texture align with the top of the screen when looking fully up.
  Thus, by using a sky texture with a height of 240 or more pixels, the sky
  will be drawn with square pixels instead of the vertically elongated ones
  imposed by Doom's native 320x200 resolution.

363dfcffbd November 12, 2009
- Improved sky stretching a bit: It now only stretches the sky as tall as it
  needs to be: 228 pixels, not 256. It no longer stretches horizontally,
  either.
  
  The reason it stretches to 228 and not 200 pixels is because Doom shifted
  its sky texture down 28 pixels. By stretching to 228 pixels, we can keep
  the sky tiled at the same height on the horizon. Skies 200 pixels tall
  (or more) will continue to tile at the center of the screen when looking
  directly ahead.

f40462dfb4 - Rewrote wide sky texture scaling again. This time, it should work for any
size textures at any scale. I also tried doing sky scrolling on the sky
  cylinder, but that didn't look so good, so I left it in screen space.

1c9b693087 - Fixed drawing of wide high resolution skies. (At least for the samples I
received. I'm not convinced that it's yet fixed for the general case.)

dda5ddd3c2 - Ported vlinetallasm4 to AMD64 assembly. Even with the increased number of
registers AMD64 provides, this routine still needs to be written as self-
  modifying code for maximum performance. The additional registers do allow
  for further optimization over the x86 version by allowing all four pixels
  to be in flight at the same time. The end result is that AMD64 ASM is about
  2.18 times faster than AMD64 C and about 1.06 times faster than x86 ASM.
  (For further comparison, AMD64 C and x86 C are practically the same for
  this function.) Should I port any more assembly to AMD64, mvlineasm4 is the
  most likely candidate, but it's not used enough at this point to bother.
  Also, this may or may not work with Linux at the moment, since it doesn't
  have the eh_handler metadata. Win64 is easier, since I just need to
  structure the function prologue and epilogue properly and use some
  assembler directives/macros to automatically generate the metadata. And
  that brings up another point: You need YASM to assemble the AMD64 code,
  because NASM doesn't support the Win64 metadata directives.
- Added an SSE version of DoBlending. This is strictly C intrinsics.
  VC++ still throws around unneccessary register moves. GCC seems to be
  pretty close to optimal, requiring only about 2 cycles/color. They're
  both faster than my hand-written MMX routine, so I don't need to feel
  bad about not hand-optimizing this for x64 builds.
- Removed an extra instruction from DoBlending_MMX, transposed two
  instructions, and unrolled it once, shaving off about 80 cycles from the
  time required to blend 256 palette entries. Why? Because I tried writing
  a C version of the routine using compiler intrinsics and was appalled by
  all the extra movq's VC++ added to the code. GCC was better, but still
  generated extra instructions. I only wanted a C version because I can't
  use inline assembly with VC++'s x64 compiler, and x64 assembly is a bit
  of a pain. (It's a pain because Linux and Windows have different calling
  conventions, and you need to maintain extra metadata for functions.) So,
  the assembly version stays and the C version stays out.
- Removed all the pixel doubling r_detail modes, since the one platform they
  were intended to assist (486) actually sees very little benefit from them.
- Rewrote CheckMMX in C and renamed it to CheckCPU.
- Fixed: CPUID function 0x80000005 is specified to return detailed L1 cache
  only for AMD processors, so we must not use it on other architectures, or
  we end up overwriting the L1 cache line size with 0 or some other number
  we don't actually understand.

8ca7c05e9d - Changed FImageCollection to return translated texture indices so
that animated icons can be done with it.
- Changed FImageCollection to use a TArray to hold its data.
- Fixed: SetChanHeadSettings did an assignment instead of comparing
  the channel ID witg CHAN_CEILING.
- Changed sound sequence names for animated doors to FNames.
- Automatically fixed: DCeiling didn't properly serialize its texture id.
- Replaced integers as texture ID representation with a specific new type
  to track down all potentially incorrect uses and remaining WORDs used
  for texture IDs so that more than 32767 or 65535 textures can be defined.

1b55520a8b - Fixed: Heretic's mace never respawned in deathmatch games.
- Fixed: At resolutions taller than 600 pixels or so, tall sky textures were
  drawn a row too low. This was quite visible on Hexen MAP06.
- Fixed: P_CheckSlopeWalk() must return false if floorsector != sector, or
  the actor will be yanked down to the floorsector by P_TryMove().
- Fixed: ClearActorInventory, GiveActorInventory, and TakeActorInventory
  only affected the first actor with the given TID.
- Fixed: The color boxes for the colorpicker menu items were drawn a little
  too low.

f618134f15 - Fixed: The MAPINFO flags that control jumping, crouching, and freelook,
rather than overriding the dmflags values, actually overwrote the dmflags
  values, so they would continue to be in effect on later maps that didn't
  explicitly specify them.

e08da03a3d - Increased precision of texture scaling factors to full fixed point. In the process
I got rid of the old tx and ty CVARs because they made the texture scaling
  much more complicated than it was actually needed (and besides, they were completely
  useless except for testing purposes anyway.)

4999c3b4aa - Fixed: Weapons did not give you double ammo at baby and nightmare skills.
- Fixed: SetTexture() in p_setup.cpp assumed that all color values were
  six characters. Although this was the intended way to specify colors,
  earlier versions did no error checking, so other lengths worked too.
- Fixed: FPatchTexture waited until MakeTexture() to call CalcBitSize(),
  so the width and height bit sizes weren't available when using it as a
  source for a warp texture.
- Fixed: R_InitSkyMap() should only warn about two sky textures not being
  the same height when they are used as part of a double sky.
- Added a NULL state check in AActor::Tick() before advancing the current
  state. Note that this should not happen, so there's an assert there for
  the debug build as well as a regular check for the release build.
