Fix issue where swingdoors would refuse to open or close if an enemy was in front of the door in an overlapping but unrelated/disjoint sector
engine.cpp: lintersect(): fix integer overflow and negative case issue
Re-introduce earlier lintersect() work that was reverted.
engine.cpp/.h: clean up & fix lintersect(). Additionally, add support for finding intersections of collinear line segments. This reverts r7290.
engine.cpp: fix crash when calling `setrendermode 3` where PolymostProcessVoxels would be called before Polymost is initialized.
PolymostProcessVoxels would call videoNextPage during processing which would attempt to render the OSD and lead to a segfault due to Polymost not being properly initialized.
polymost.cpp: temporarily disable experimental r_enablepolymost2 cvar
polymost.h: fix order of parameters to match polymost.cpp
polymost.cpp: fix lockup bug that would occur with polymost_waitForSubBuffer() when glClientWaitSync consistently returned GL_WAIT_FAILED on certain hardware/drivers.
Additionally, fix conditional check for r_persistentStreamBuffer requirements in polymost_glinit().
polymost.cpp/glsurface.cpp: Don't print shader compile status to the console on success.
Support software renderer upscaling engine-side in sdlayer and sdlayer12 with various scaling factors (beyond just pixel doubling).
When glsurface is available, use GL to upscale the render buffer. Additionally, fix build issues with sdlayer12 introduced by GLAD changes (r6656).
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
Additionally, fix issue in polymost_setShade() where shade calculation was happening after a check for whether or not the shade needed to be updated.
sdlayer.cpp: fix software renderer crash affecting Mapster32 due to improper handling of lockcount in videoBeginDrawing()/videoEndDrawing() when using glsurface
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.
astub.cpp: fix issue where globalpal was not declared if polymost.h was not included
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.
This could occur when returning to 2D mode from 3D mode in Mapster32 as videoSet2DMode() does not affect the result of videoGetRenderMode() despite destroying the 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:
+avoid adding the pivot's z offset again after it was already added in classicDrawSprite() +offset the voxel object by half of the voxel object's z size
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.
Temporarily remove the option to enable texture filtering when building with EDUKE32_STANDALONE until indexed colour texture rendering supports filtering.
menus.cpp: disable palette emulation menu options when in Polymost and r_useindexedcolortextures is 1
menus.cpp: Allow setting anisotropy when not in Polymost regardless of whether r_useindexedcolortextures is set
polymost.cpp: fix shadeFactor not being set properly for non-indexed colour textures
center texel fetches for palette lookups and add various optimizations related to indexed texture changes
Polymost palette-indexed texture rendering
polymost.cpp: fix polymost_dorotatesprite() issue where sprites could be rendered with fractional positions and sizes leading to GL filtering imperfections.
