/* TOS needs screen width to be aligned to 128/planes and height to VDI text
|
||
* height (16, larger of these, is used in calculating the limits in Hatari).
|
||
* Max. screen size supported by EmuTOS (and TOS v3.x?) is 300kB.
|
||
*
|
||
* Below MAX_VDI_* values are reasonable limits for monochrome resolutions.
|
||
* 300kB limits screen size to max. resolution of 2048x1200 or 1920x1280,
|
||
* which allows FHD (1920×1080), WUXGA (1920x1200) and QWXGA (2048x1152)
|
||
* standard resolutions.
|
||
*
|
||
* On 4-color mode, 300kB limits screen size to 1280x960 or 1200x1024
|
||
* which allows HD (1280x720), WXGA (1280x768) and XGA+ (1152x864)
|
||
* standard resolutions.
|
||
*
|
||
* On 16-color mode, 300kB limits screen size to 1024x576 or 800x768,
|
||
* which fills nicely qHD (960x540), DVGA (960x640) and WSVGA (1024x600)
|
||
* standard resolution displays.
