What changed in EDuke32, build by build

Factor out rendering tests for whether a sprite is a voxel

fix transparent floor/ceiling double drawing

fix editor sprite select in TROR sectors

bare bones editor check for models

add invalid polygon check in editor mode

Fix flipped HUD model rendering

fix NPOT tile rendering when hightile option is disabled

center texel fetches for palette lookups and add various optimizations related to indexed texture changes

workaround for texcache expecting all mipmap levels to be available

fix typo causing bug where persistentStreamBuffer was being reset to the config value when it should be disabled

fix bug where polymost2_drawVBO() wouldn't reset the bound buffer state properly for polymost1

adjust parenthesis to cease compiler warnings

streaming VBO optimizations for polymost_drawpoly()

Avoid generation of mipmaps if filter mode isn't set to use them

texture format optimizations

Account for yscale when deciding if the sky is tall enough to repeat or not. Comment out code that is not working as expected.

Set r_parallaxskypanning to 1 by default.

Display paper-skies correctly when looking up or down.

New projection hack algorithm: Keep zoom equivalent to Classic when looking straight ahead.

Fix yoffset bouncing of face sprites with cstat 128.

Don't cut off a row and/or column of texels when drawing floor-aligned sprites with odd dimensions.

fix texture panning floatiness on slight slopes

Clear wsprinfo[] upon map load. This should address some remaining instances of wall-ornamented sprite z-fighting.

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.

Tweak the "don't upload textures with dimension > xdim" GL ES rule to limit to the power of two greater than xdim instead of less than it.

Clean up and rearrange some texcache code. No functional changes.

Call texcache_calcid once per texture instead of twice. Clean it up a little while we're at it.

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