This is quite a big update that mainly changes the size used for render targets and re-introduces the correct usage of texture coordinates instead screen coordinates by the shaders.

Refactored render targets

HLSL now uses NPOT sized render targets (this breaks the compatibility with graphics cards based on R300/R400/NV30, anno 2005 and older)
HLSL render targets now have the exact size of the screen
removed HLSL pre-scale factor
improved overall performance (based on the previously required pre-scale factor, you might notice a 5-50% speed-up depending on your graphics card, more if you used a higher pre-scale factor)
improved shadow mask quality (pixel-perfect) in screen-mode
HLSL now uses a sharp bi-linear interpolation to pre-scale textures to screen size, based on [Themaister's] implementation
added proper texture coordinates to vector screen quad
removed ./hlsl/artwork_support folder (the default shaders supports artworks again)
known issue: cocktail mode for vector screen looks wrong

Improved scanline simulation

changed the amount of scanline darkness, a setting of 1.0 now becomes fully black (to get the same result as before half your current setting)
added scanline variation, which makes the scanline height dependent on the brightness of the underlying color
the amount of the scanline brightness and overdrive now depends on the scanline darkness
renamed 'Scanline Screen Height' to 'Scanline Screen Scale' and 'Scanline Indiv. Height' to 'Scanline Height'

Refactored bloom

fixed dimensions of bloom targets, which results in a much better alignment especially for games with very low resolution (therefore current bloom settings might look a little less intense than before)
reduced blur width for raster screen
added usage of shadow u/v option for source tile mode

HLSL presets

added general presets for raster and vector screens
added example presets for Game Boy (monochrome LCD) and Game Boy Advance (color LCD)
options are now reset to loaded preset when game is closed

MAME Testers #06144: Fixed infinite loop

fixed infinite loop while building slider list, when more than one window was created

p.s. The fix for #06144 is more of a workaround, because it doesn't achieve the intended functionality, but at least the application does not freeze anymore
