fix a possible crash with texel-hitscan.
Reproduced as follows (assuming all tiles have texel-hitscan for simplicity): In E2L5, shoot the opening switch with the shotgun, aiming for the border. The crash occurs because the *other*, depressed switch tile isn't yet loaded when we index into its tile storage. Dereferencing 0+small number == BAD!
in setaspect_new, determine the aspect with {x,y}dimen instead of {x,y}dim.
That is, use the view boundries instead of the whole screen.
fix unused variable permanentlock
make neartag accept a sprite-blacklist function and use it in sector.c.
Internally, the last argument to neartag is now a pointer to a function int32_t (*blacklist_sprite_func)(int32_t i), which is supposed to return 1 if sprite[i] should NOT be considered for hitting. This is now used in the hard-coded neartag() calls in sector.c, but not in any way in CON (there's neither a C blacklist function provided, nor is there a possibility to define one in CON). There, all sprites with picnums >=1 and <=10 (i.e. the effectors) will be blacklisted. This remedies problems where such sprites would get in the way of switches. Note that a whitelist approach (only consider a predefined set, namely those picnums which will be checked afterwards) has back-compatibility implications since people may have used e.g. lotagged window sprites to cover a switch. Also, the >=1 to <=10 range is [sic] (the static, not dynamic values are used), since anyone redefining effector picnums is clearly out of their mind.
make smoststart[] (which saves starting "smostcnt"s) an array of int32's
instead of shorts. This fixes their values' overflow in AMC TC megabase and probably a couple of other large maps.
add funtion 'yax_vnextsec(wall, cf)' to C API. It's often useful when
dealing with sectors on the two sides of a bunch. Make yax_globallev and yax_globalbunch variables non-static. Rewrite a TROR-related bit in the engine code using the new function.
In setbrightness() and qsetmodeany(), call setpalette() only if the
palette changed from the last one (either globally or within the last call of one of the function). This fixes the ugly OSD flickering in 8-bit mode when a screen tint effect is in action (such as when being hurt or snotted on).
