What changed in EDuke32, build by build

game.h: fix calc_smoothratio_demo() to take into account differences between timerGetClockRate() and TICRATE when calculating the refresh frequency to interpolate between

polymost.cpp: fix buffer overflow issue in uploadpalswap() & correct the code to initialize an extra row of black pixels

clockticks.hpp: Fix issue where higher precision comparisons would cause unexpected behaviour with game loop code due to ototalclock being incremented rather than set to totalclock (causing a lack of subtick precision and potential doubled up/dropped game updates).

kenbuild/src/game.cpp: Fix compilation issue due to removal of sqr() from pragmas.h in r7597

Change some clocks to support sub-tick precision using a new class, ClockTicks.

timer.cpp: fix order of operations issue with timerUpdate()

sounds.cpp: fix infinite loop caused by removal of "else" in r7939

Fix issue with indexed colour textures where in the case that tiles entered the texcache while !waloff[picnum] & were later (re)loaded, the earlier pth pointing to the tilesheet containing the blank tile would never be properly replaced with an updated gl texture.

gameexec.cpp: allow G_ShowView() to execute regardless of the state of g_screenCapture.

tiles.cpp: backup & restore picsiz, walock, & waloff alongside other per tile arrays in artClearMapArt() and artSetupMapArt()

engine.cpp: make renderSetTarget() more robust so that passing an xsiz or ysiz <= 0 is not accepted and can't cause a segmentation fault

polymer.cpp: fix issue where assert could fail due to HUD model sprites having an owner >= MAXSPRITES

polymost.cpp: Fix issue where tiles whose dimensions had grown would not have their sizes updated in GL and could fail to update their texture data

Fix mixing offscreenrendering (render targets) and mirrors. Don't allow recursing beyond 1 level of mirroring through multiple levels of render targets.

Fix rendering skyboxes to a tile by altering renderSetTarget() & renderRestoreTarget() to set & reset xdim & ydim so that G_ShowView() can render while a render target is set,

Fix edge case where mirrors & TROR could interact and render over skyboxes in the classic software renderer

Fix parallel build by switching to generating .obj files from .glsl files and treat the shader source as an externed global resolved at link time.

osdfuncs.cpp: fix OSD background sometimes not rendering with the correct gl state

Fix 32-bit Polymost issues by enabling SSE instructions and setting GCC to use SSE floating point math exclusively.

polymost.cpp: Fix polymost_domost() issue with COMBINE_STRIPS where in certain cases, merging with the viewport nodes caused accidental reading of sentinel node values.

winlayer.cpp: fix videoBeginDrawing() to return an intptr_t to mirrorBuffer when inpreparemirror

Fix TROR & skyboxes to work with mirrors in Software & Polymost

game.cpp: fix issue where tilt angle was not being reset to 0 at times when it should have been disabled

Fix latency issue introduced by G_FPSLimit() handling of videoNextPage() that was causing frames to be delayed presentation until after the next frame is prepared.

engine.cpp: fix sprite sorting/adjustment issue introduced in r7612 that caused sprites with the same y value at the end of the sorted array to not be adjusted properly

polymost.cpp: Fix issue where state would not be reset properly in polymost_drawmaskwall() when rendering translucent maskwalls with no texture

polymost.cpp: fix polymost_dorotatesprite() alpha test/blend issue introduced in r7619

polymost.cpp: fix issue where floors & ceilings with DAMETH_MASKPROPS were not being blended

engine.cpp: fix bug in killsprite where sprites were not being removed properly after sorting changes
