- Fixed: cycle_t was still a DWORD and not a QWORD under GCC. - The stat meters now return an FString instead of sprintfing into a fixed output buffer. - NOASM is now automatically defined when compiling for a non-x86 target. - Some changes have been made to the integral types in doomtype.h: - For consistancy with the other integral types, byte is no longer a synonym for BYTE. - Most uses of BOOL have been change to the standard C++ bool type. Those that weren't were changed to INTBOOL to indicate they may contain values other than 0 or 1 but are still used as a boolean. - Compiler-provided types with explicit bit sizes are now used. In particular, DWORD is no longer a long so it will work with both 64-bit Windows and Linux. - Since some files need to include Windows headers, uint32 is a synonym for the non-Windows version of DWORD. - Removed d_textur.h.

extern "C" int ds_color; // [RH] For flat color (no texturing)
- 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)
