Cosa è cambiato in EDuke32, build per build

fix regression with Y-flipping bit.

add preliminary support for batching draws.

fix synthesis warning.

store map data in a single buffer with a unified vertex type.

further 2d mode performance improvements. Sprites are also now displayed with their xrepeat and yrepeat taken into account. It's not perfect yet... needs more "jiggery-pokery"

fix two "variable may be used uninitialized" warnings.

fix a possible oob read via drawspritelabel; sanitize 2d3d mode.

2d mode performance improvements

improve 2d mode sprite label display. I want to test this further, so this is marked as DONT_BUILD.

fix 3d picture-in-picture when editing a map with TROR.

improve diagnostic message.

A couple of Mapster32 tweaks to play nicer with different palettes.

Address complaints from the "Mapster32 problems and bugs" thread.

Mapster32 changes:

New experimental Mapster32 hybrid 2D/3D mode feature. Pressing F10 in 2D mode enables a picture-in-picture 3D view in the corner of the screen. When moving the mouse over the 3D view, the controls change to 3D mode controls and all 3D mode operations can be performed. The 3D view can be resized with shift + F10 and can be moved to different positions by holding CTRL and using the arrow keys.

Enable sector drawing and textured map in Mapster32 sideview mode with a sideview elevation of 512 (straight up and down).

Improve r_preview_mouseaim and Polymost Mapster32 3d mode mouse selection. Also adds a display of the current coordinates, angle and horiz when moving around in 3d mode.

Slight further Polymost cleanup. Nothing of real importance. DONT_BUILD.

Fix automap lines in Polymer mode

fix an oob write in test_map().

mdsprite.c: from updateanimation(), if m->[cn]frame >= numframes, clear to 0.

Re-expose kpzbufsiz and set it to zero in uninitengine, preventing potential crashes from successive re-initializations of the engine.

Set htg_t 6, 7, and 8 on GROWSPARK sprites upon shooting, as is done for all other hitscan projectiles.

Make 'L' key toggle grid lock in 3D mode, because it affects placement of sprites inserted with 'S'.

fix rendering of middle part of 1-way masked wall.

Parallaxed skies.

Add uint32_t PaletteIndexFullbrights[8] so that Polymost can respect the lack of fullbrights in KenBuild and Shadow Warrior.

Since sprite->filler is now fogpal, modify the CTF code that uses it to use a new variable in SW's USER struct instead.

setsprite, setspritez, getzrange, clipmove, pushmove, neartag, dragpoint, screencapture, md_tilehasmodel, preparemirror, saveboard, loadboard, pos

honor r_usenewaspect, especially it being off.

Add support for ART files containing exactly one tile as an input format for hightile textures and model skins. They are rendered in the global game palette and function as conventional hightile.
