Fix sprite sizes

[ghost]

HLE sprite sizes were 1pixel smaller than LLE sprite sizes when not in copy mode.
Fixes #936

Edit: I made a mistake while testing yesterday. A second commit was necessary.

The g[s]SPObjRectangle GBI draws texture for the rectangle area defined by the upper left hand corner screen coordinate (objX, objY), and lower right hand corner screen coordinate (objX+imageW/scaleW-1, objY+imageH/scaleH-1). The drawn texture region will be defined by upper left hand corner (0,0) and lower right hand corner (imageW-1, imageH-1). If scaleW and scaleH are 1 << 10, texture will be drawn with equal proportions, without scaling.

the texture for the rectangle is -1.

@olivieryuyu Yes, however OpenGL takes the coordinate on the right side of the pixel which is (imageW, imageH), which is handled in gSPDrawObjRect(). Shifting rectangle position by approximately 0.5 almost gives correct results with (imageW, imageH) coordinates, but there are precision errors that make it impossible with current code.

I put this fix to 'fix_sprite_size' branch. It needs testing. I foresee regressions in 2D games. Good if I'm wrong.

Appears to fix Magical Tetris Challenge #246:

LLE is broken in a different way:

[olivieryuyu]

done some tests and if regresssion there is, it is not obvious.

I'll include it to next WIP build. May be somebody will find something wrong. Otherwise it will be put to master.
