What changed in EDuke32, build by build

polymost.cpp/glsurface.cpp: Don't print shader compile status to the console on success.

menus.cpp: Don't show texture filtering, anisotropy, or palette emulation options when EDUKE32_STANDALONE is defined

Support software renderer upscaling engine-side in sdlayer and sdlayer12 with various scaling factors (beyond just pixel doubling).

sdlayer.cpp: Don't destroy window resouces if switching between software rendering on glsurface and Polymost/Polymer

polymost.cpp: make c_wrapThreshold consistent between POLYMOST1_BASIC_FRAGMENT_SHADER_CODE and POLYMOST1_EXTENDED_FRAGMENT_SHADER_CODE

polymost.cpp: fix rendering for indexed colour textures to match original behaviour when !r_usetileshades or globalflags & GLOBAL_NO_GL_TILESHADES

sdlayer.cpp: fix software renderer crash affecting Mapster32 due to improper handling of lockcount in videoBeginDrawing()/videoEndDrawing() when using glsurface

glsurface.h/.cpp: change how the palette is handled and fix tinting/fading

Revert a number of changes from r6929 and r6930 that are no longer necessary.

Add glsurface.cpp/h and tilepacker.cpp/h to Visual Studio Project

Don't allow GL modes if GL Major Version is less than 2.

sdlayer.cpp: don't alter desktop composition using win_setvideomode() if we're creating an SDL window for rendering GL

When OpenGL is available, prefer using the new glsurface to blit the classic renderer's 8-bit buffer to the screen.

tilepacker.cpp: instead of maintaining the heap on each insertion, maxheap_buildHeap() on tilepacker_pack()

anim.cpp: timerUpdate() before setting the start time of the animation so that delays outside of animation playback won't cause animations to skip

astub.cpp: fix issue where globalpal was not declared if polymost.h was not included

palette.cpp: don't call uploadbasepalette() if USE_OPENGL is not defined

engine.cpp: fix issue introduced in r6905 where voxels with fractional scaling would not be handled correctly in Polymost

tiles.cpp: fix texcache.cpp:CLEAR_GL_ERRORS() hang on some drivers when trying to create GL textures for tiles when we have no GL context.

engine.cpp: fix issue with voxmodel_t voxels not having their scale set properly due to defs being processed before PolymostProcessVoxels()

engine.cpp: fix classicDrawVoxel() positioning bugs by:

actors.cpp: improve SE_11_SWINGING_DOOR detection and handling of players that block a door's path

polymost_drawpoly(): fix issue where mirrors wouldn't update the depth buffer

G_HandleMirror(): When choosing which mirror to render, only choose from mirrors that are potentially visible.

engine.cpp/.h: clean up & fix lintersect(). Additionally, add support for finding intersections of collinear line segments.

polymost_bindPth(): Fix issue where non-indexed colour, non-hightile textures (including those with polytintflags HICTINT_USEONART or HICTINT_ALWAYSUSEART) would not render correctly while r_useindexedcolortextures is set.

Incrementing ud.executions is now done in app_main() instead of CONFIG_WriteSetup() so that it is only incremented once per execution.

Dynamic tilepacking for indexed colour textures

ud.showfps > 2 now shows Game Update time and Game Update & Draw time (along with the min & max Game Update time) for easier performance analysis

polymost_resetVertexPointers(): remove erroneous glBindBuffer call

Temporarily remove the option to enable texture filtering when building with EDUKE32_STANDALONE until indexed colour texture rendering supports filtering.

Switched Duke3D to use new LZ4 dfwrite()/kdfread() implementations to improve compression/decompression speed.
