[Hero, G2 Touch Android Development] sotux:
Hi, I tried to build CM7 for my htc hero recently and I found the build.prop generated by the build system was a mess. So I changed some make file.

But I don't know whether my change is totally correct. So I want to share my make files and have a discuss.

First file is BoardConfig.mk

I reference some code from dream_sapphire. I found set BOARD_AVOID_DRAW_TEXTURE_EXTENSION := true seems improves 2D rendering especially the popup window in Gingerbread.

I'm not sure those properties I marked with #------------- is necessary.

But after I built the rom, the phone worked well.
