What changed in EDuke32, build by build

SDL 2.0.5

Don't set the window icon from code if we are linked with SDL >= 2.0.5 on Windows, since it will now automatically use the first icon in the exe.

Add EDUKE32_SDL_LINKED_PREREQ macro.

Disable Windows thread naming because it interferes with debugging.

Implement "divscale" and "scalevar" (scale()) in C-CON and "scalevar" in M32script.

Fix improper matching of loop tags with initial substrings of them, and add proper support for LOOP as a synonym of LOOP_START.

Bump PSKYOFF_MAX from 4 to 8.

Add "yoffset" subtoken to "multipsky".

Re-enable the use of psky_t's yoffset.

Fix addlogvar command, broken in r5835.

GL .blend support.

In 8-bit, change the precedence of .alpha and .blend.

Cosmetic changes to some blend/alpha related code.

Don't unpause sounds when exiting the menu back to a Game Paused state.

Remove the Polymer aspect ratio option, as it was always broken, and I don't know what purpose it has besides configuring non-square pixel stretching, which we have a long way to go in terms of configuring anyway.

Fix clang Windows build. DONT_BUILD.

Fix mistake in r5862. DONT_BUILD.

Fix erroneous display of MESSAGES: ON when it should be OFF.

Fix TEST_SYNC_KEY macro to always return 1 or 0.

Allow an invocation like `make CC=clang-3.8` to work properly.

Fix undefined behavior: null pointer passed as argument which is declared to never be null

Loop optimizations in screencapture

Fix ghost tsprite bug introduced in previous commit.

Finish what r5484 started but got reverted in r5723. Cstat 1024 now works properly in Polymost without causing any side effects in Classic. It remains unimplemented in Polymer.

Reinstitute the cosmetic cleanups that should have been a separate commit from r5484 and were reverted in r5723.

Fix MIDI playback on Windows, broken in r5817.

Fix warning: signed and unsigned type in conditional expression [-Wsign-compare]

Fix a bug in r5826 regarding display of the WWII GI rocket launcher.

Add bit 1 to action flags: use the viewpoint's position relative to the actor when calculating which rotation to display, instead of the viewpoint's angle, for viewtypes 2/3/4/8. 5/7 already do this.

Add an optional sixth parameter, a flags bitfield, to action definitions. Bump BYTEVERSION.

Enumify stuff having to do with action parameters.

Satisfy warning: this 'if' clause does not guard... [-Wmisleading-indentation]

Fix warning: logical 'and' of equal expressions [-Wlogical-op]

Fix warning: left shift of negative value [-Wshift-negative-value]

Fix simple_array operator[] parameter type.

Correct an oversight in r3580.

Revert part of r5481. We can't rely on the sprite trackers to tell us when tsprites change.

Restore some accidentally-working cases of SEs 5, 6, 14, and 30 broken in r3161.

Fix build on OpenBSD. DONT_BUILD.

Revert r5658. This fixes the disappearing chaingun problem.

In uploadtexture, don't assume that a non-masking texture can safely be sent to the driver without the alpha channel.

Fix the oversight in handling tspr->extra from r5400 by setting it to zero in polymer_scansprites.

Remove trailing whitespace from anything we don't need to rebase from an upstream.

Add some preprocessor checks on the output format to the asm.

Create GTK *_banner.c files in obj/ subfolders instead of rsrc/ so that they don't need separate cleanup rules.

Make Objective-C code build as Objective-C++ when we build C code as C++.

Add extra optimization defaults for OS X builds since all Intel Macs are guaranteed certain features due to the time of their debut.

Clean up handling of architectures.

Remove unnecessary asm unprotection of ylookup[].

Clean up self-modifying assembly unprotection and add PROT_EXEC to mprotect() calls.

Clean up creation of SDL_Renderer and provide information about the process to the log.

Clean up fallback video mode attempt code in order to fix at least three bugs.

A small patch from rhoenie to make our source compatible with the Intel C Compiler.

Update ignore rules.

Fix build. BUILD_LUNATIC.

Convert object lists to an escaped multi-line format for better diffing.

Add some missing dependencies on the folders in which objects are created.

Add L_CXXONLYFLAGS, and use it to pass "-static-libstdc++" on Windows.

Reorder preprocessor lines in libdivide.h so that LIBDIVIDE_USE_SSE2 is defined before emmintrin.h is included. Fixes ticket #23. DONT_BUILD.

More Android build changes. DONT_BUILD.

A quick hack so that Mapster can load more pre-v7 PALETTE.DAT files.

Some stuff for using clang to build on Android. DONT_BUILD.

Enable LIBDIVIDE_USE_SSE2 under x86_64 builds or if the binary is built with SSE2 optimizations.

GL ES: Interpreting glGetError as always meaning "this internal texture format doesn't work" is too dangerous to keep in the live code (not to mention wasteful). Move it to a new and improved Polymost_InitDummyTexture, now called Polymost_DetermineTextureFormatSupport.

Factor out the ETC block preparation by moving the ETC function decision from Polymost_SendTexToDriver into Polymost_PickETCFunction.

Allow compressed ART tiles (r_texcompr 2) to be cached.

You'll Cowards Don't Even Indent

Small tweaks to Android.mk.

Add a hack so that when exit() is called on Android, we instead longjmp to main() and return from there.

Add "artquality" subtoken to textures, model skins, and skyboxes, which grants the texture HICR_ARTIMMUNITY. In effect, this implies "nodownsize" and signals that texture compression would be undesirable, but okay using r_texcompr mode 2 (aggressive).

In polymost_glinit, pass a dummy 4x4 texture to uploadtexture in order to detect what compressed texture formats are acceptable without wasting time compressing the first texture it encounters, such as the 3D Realms screen, in case the graphics chip won't take it.

This seems like a bugfix.

Fix shading on ART tiles with fullbrights displayed without masking, such as on a whitewall.

Adjust the way bottom edges are clipped in rotatesprite to better handle tall text, or text with long Q tails.

A potential fix for the "loading sounds and music from zip files" bug.
