sorry i find where i was mistaken yes indeed the framebuffer size will be one especified,
and in full screen it wil be rescaled automatic , my concern was to rescaling a part of the frambuffer
, im just blittin an area of 800x600 and if the resolution grows there will be an empty space surrounding the framebuffer beacuse nothing is render beyond 800x600,but even rescaling that part of the buffer to fill the empty spaces just going to mess with my mouse input.
i dont know what i think of this in first places...after all reading the post it fells weird so i guess im going to keep working with 800x600 and perhaps 1024x768 anyway i think im overthinking this reslution thing.
sorry for the confussion and thanks for kepping track of thigs like this
