* NOTE: ACQUIRE / RELEASE screen pair must work same way DispBegin()/DispEnd() pair does
|
|
* (that is, with an internal counter), as lots of function may want to 'acquire/release' it.
|
|
* However, a GT must properly manage its gfx output if the user didn't requested to acquire the
|
|
* screen, so this is under user choice.
|
|
* (the user just needs to know that it is not the same to aquire the screen, draw 100 lines, then
|
|
* release screen, than simply drawing 100 lines -as the GT will be acquiring/releasing the screen
|
|
* 100 times, which will slow down things a lot-) [Mauricio]
