- Discovered that Shader Model 1.4 clamps my constants, so I can't use 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. SVN r640 (trunk)

- Fixed: The names in the Depths array in m_options.cpp were never freed. - Fixed: FDoomEdMap needed a destructor. - Fixed: Decal animators were never freed. - Fixed: Colormaps were never freed. - Fixed: Memory allocated in R_InitTranslationTables() was never freed. - Fixed: R_InitParticles() allocated way more memory than it needed to. (And the particle memory was never freed, either.) - Fixed: FMetaTable::FreeMeta() should use delete[] to free string metadata. - Fixed: FConfigFile::ClearCurrentSection() must cast the entry to a char * before deleting it, because that's the way it was allocated. - Fixed definitions of DeadZombieMan and DeadShotgunGuy in doom/deadthings.txt. Skip_super resets the dropitem list, so having it after "DropItem None" is pointless. - Fixed: Decorate DropItem information was never freed. - Fixed: FinishStates() allocated even 0-entry state arrays. - Fixed: Default actor instances were never freed. - Fixed: FRandomSoundList never freed its sound list. - Fixed: Level and cluster strings read from MAPINFO were never freed. - Fixed: Episode names were never freed. - Fixed: InverseColormap and GoldColormap were never freed. Since they're always allocated, they can just be arrays rather than pointers. - Fixed: FFont destructor never freed any of the character data or the font's name. - Fixed: Fonts were not freed at exit. - Fixed: FStringTable::LoadLanguage() did not call SC_Close(). - Fixed: When using the -iwad parameter, IdentifyVersion() did not release the buffer it created to hold the parameter's path.
