palettes smaller than 256 entries with the shader I wrote for it. Is there
a list of gotchas like this listed some where? I'd really like to see it.
Well, when compiled with SM2.0, the PalTex shader seems to be every-so-
slightly faster on my GF7950GT than the SM1.4 version, so I guess it's a
minor win for cards that support it.
- Fixed: ST_Endoom() failed to free the bitmap it used.
- Added the DTA_ColorOverlay attribute to blend a color with the texture
being drawn. For software, this (currently) only works with black. For
hardware, it works with any color. The motiviation for this was so I could
rewrite the status bar calls that passed DIM_MAP to DTA_Translation to
draw darker icons into something that didn't require making a whole new
remap table.
- After having an "OMG! How could I have been so stupid?" moment, I have
removed the off-by-one check from D3DFB. I had thought the off-by-one error
was caused by rounding errors by the shader hardware. Not so. Rather, I
wasn't sampling what I thought I was sampling. A texture that uses palette
index 255 passes the value 1.0 to the shader. The shader needs to adjust the
range of its palette indexes, or it will end up trying to read color 256
from the palette texture when it should be reading color 255. Doh!
- The TranslationToTable() function has been added to map from translation
numbers used by actors to the tables those numbers represent. This function
performs validation for the input and returns NULL if the input value
is invalid.
- Major changes to the way translation tables work: No longer are they each a
256-byte array. Instead, the FRemapTable structure is used to represent each
one. It includes a remap array for the software renderer, a palette array
for a hardware renderer, and a native texture pointer for D3DFB. The
translationtables array itself is now an array of TArrays that point to the
real tables. The DTA_Translation attribute must also be passed a pointer
to a FRemapTable, not a byte array as previously.
- Modified DFrameBuffer::DrawRateStuff() so that it can do its thing properly
for D3DFB's 2D mode. Before, any fullscreen graphics (like help images)
covered it up.

if present.
- Modified GZDoom's true color texture copy functions and added them
to generate 32 bit D3D textures. Paletted TGAs and PCXs are also handled
this way but I don't think these 2 formats are worth some more special
handling.
(Question: Is it worth it to implement special handling for paletted PNGs
so that they are used as 8 bit textures internally?)

They are not actually drawn with it yet, nor is it complete, but it's
something to start with.
- Split up DCanvas::DrawTexture() into more pieces to make it easier to
virtualize.
- Removed support for non-32-bit palette textures from D3DFB. What kind of
card supports pixel shaders but not 32-bit textures?
SVN r605 (trunk)
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.)

bWorldPanning flag. Also added some NULL pointer checks to the
hires texture loading code.
- Added Sector_SetFloorScale2 and Sector_SetCeilingScale2 line specials.
They are mostly the same as Sector_Set*Scale but take fixed point parameters.
This makes them easier to use and more precise than the old ones which
offered very small fractional precision.
- Changed Thing_Deactivate so that passing a tid of 0 deactivates the calling
actor.
- Added MeansOfDeath parameter to DamageThing.

data file.
- Removed the setcolor CCMD. It's been obsolete for years, ever since color-
aware cvars were added.
- Changed V_GetColorStringByName() to return an FString, because it did a
copystring() call.
- Extended V_GetColorFromString() so that it accepts HTML-style #RRGGBB and
#RGB color strings.

The lump is open anyway at that time so deferring this action until the information
is needed doesn't give any speed improvements. Now GetDimensions and all its
associated overhead is gone.
- Added support for TGA textures. It can handle all of the common variations
of this format.
- Changed: GI_PAGESARERAW is no longer checked. It wasn't really necessary before
because the chance of texture misidentification is absolutely minimal.
But raw pages are now restricted to textures of type TEX_MiscPatch only.
- Changed the automap parchment to use a regular texture. The previous
FAutomapTexture is only used as a last resort fallback now. If the code
finds a recognizable graphic it will create a proper texture for it now.
- Fixed: Flats were only auto-scaled when in Doom flat format.
- Fixed: FMultiPatchTexture::CheckForHacks blindly assumed that all patches
were FPstchTextures. Since the texture code does not have any type information
I added a new flag bIsPatch for this purpose.
- Moved all texture classes into their own source files and created a new
subdirectory 'textures' for that.
- Cleaned up the texture management code and added some stricter checks for
the validity of Doom patches. The old code liked to crash when being passed
some non-graphic data.
