Bug: style001.gry bridge texture artifacts
Image: http://picasaweb.google.com/under.northern.sky/OpenGTAScreenshots/photo#5015284379944604402
black pixel inside a side texture (nyc.cmp)... thus begins the
'how many errors can there be about black vs. transparent contest'.

Bug: wrong block texture coords
Image: http://picasaweb.google.com/under.northern.sky/OpenGTAScreenshots/photo#5015284384239571746
Status: maybe-closed
Most likely the side that is a triangle and not a quad.
Needs research if 'flipping' the texture is related.

Update: fixed for the case shown in the screenshot; may lurk on north/south sides of
blocks, flipping/rotation influence remains unknown.

Bug: transparent pixel in g24 tiles
Image: http://picasaweb.google.com/under.northern.sky/OpenGTAScreenshots/photo#5052612481245901378
Those should probably just be black. It is not a very obvious
error, but it should be fixed.

Bug: black border around sprites
Image: http://picasaweb.google.com/under.northern.sky/OpenGTAScreenshots/photo#5052612481245901394
Simply doesn't look good, especially with g24 graphics.
%%
Bug: wrong-player position in viewer.exe when switching from free mode (F4)
A position somewhat ~north~ is actually used; if you are at the north-border of the
city this can cause the player to be spawned outside 0->255 ^2 range, which exits
the program.
%%
Bug: wrong walk/run animations when armed
Switching between forward/backward/run often changes the weapon as well; walking
forward with the gun doesn't work at all.
%%
Bug: scale2x disabled in all previous releases
The script prepare_build.sh defines -DDO_SCALEX while the code actually is
activated by -DDO_SCALE2X; errare humanum est.

This bug will be closed when the next release includes this feature; otherwise
see cvs.
%%
Bug: switching to/from fullscreen (at runtime) is broken on Windows (again?)
Most polygons are plain white, some strange rendering errors appear as well; 
aka. oh gl-context, where did all my textures go?

Does this affect switching the screen resolution as well? Probably :-(
%%
Bug: vertical sync - SDL_GL_SWAP_CONTROL
Does not work in the Win32 binaries, the SDL version I used is too old.

Stopped doing anything on at least my Linux system (after an update) as well.
%%
Bug: Data _or_ interpretation - block type
Image: http://picasaweb.google.com/under.northern.sky/OpenGTAScreenshots/photo#5060057403938727394
Several problems may stem from the 'flags stored in block above the one with the graphic' gta-
legacy. The symptom is: you can fall through some floor blocks!

Probably several cases exist; either a bug in my code or some quirk of the map format.
%%
Bug: Collision with 'flat' blocks
Partially transparent blocks (sign posts, fence, etc.) need special rules to handle
blocking of peds/projectiles/car; implemented only for peds.

Furthermore only works on nyc.cmp, need to research the tile-ids for the other style
files.
FIXME: which blocks should _not_ block projectiles?
%%
Bug: Pedestrian movement physics

1) Moving up/down on a slope should influence speed

2) You can walk up a single vertical wall (can be seen when walking on roofs;
probably also teleports to the upper road when under the bridges in nyc.cmp.
