- Fixed: FTexture::~FTexture() must destroy the associated native texture
if present. - Modified GZDoom's true color texture copy functions and added them to generate 32 bit D3D textures. Paletted TGAs and PCXs are also handled this way but I don't think these 2 formats are worth some more special handling. (Question: Is it worth it to implement special handling for paletted PNGs so that they are used as 8 bit textures internally?) SVN r608 (trunk)

|

- Fixed: DCanvas::Blit unlocked the destination twice instead of unlocking
|
||||
both dest and src. Also changed this function so that it is owned by the
|

destination canvas of the operation which is necessary if it needs to
