raze-gles/polymer/eduke32/build/src/osd.c
helixhorned 51fb860650 * Thin out models in memory by removing unused frames. This saves 200MB with DNE on Polymer. 
* fix memory corruption when loading a Polymer savegame using another renderer and then change to Polymer
* fix possible crash in OSD_Exec() and uninitialized mem access in game config reader
* move makeasmwriteable() to baselayer.c
