Comment (by BallM4788):

 Replying to [comment:4 ccawley2011]:
 > Most memory allocation in TinyGL is done using the wrapper functions in
 graphics/tinygl/memory.cpp, so a good way to get started is to edit that
 file to use the linear allocation functions instead of the stdlib ones and
 see how well it works.
 See my comment above.
 Also, I tested out [https://github.com/scummvm/scummvm/pull/4973 your pull
 request] in combination with my changes above, and the results were as
 follows:
 * For Grim Fandango, the screen remains black, and doesn't seem to ever
 finish loading. No crashing though, it just stays stuck on the black
 screen.
 * For The Longest Journey, the screen also remains black, but stuff is
 loading behind the scenes as all the audio plays properly.
 * After launching either game, if the user attempts to bring up the pause
 menu, the screen remains blank.
 I have no clue why putting TinyGL's Z-buffer on the linear heap would
 cause the screen to go blank. It clearly has no problem putting texel
 buffers on the linear heap...
