Update CGameMenu.cpp

[PrIzRaKDev]

Changes:

• Fixed a bug where the CTexture_DrawInRect call was manually inserted into the code, which could cause stack alignment issues.
• • Fixed a bug where the posX and posY variables were declared without initialization.
• Fixed a bug where the code did not check for errors when calling the MemoryNop and MemoryJump functions.
• Added a check that the CTEXTURE_DRAW_BG_RECT function call address is valid before inserting a hook.
• Stack clearing with pop ebp added to OnDrawMenuBackground function to properly restore the stack after calling CTexture_DrawInRect.
